ZIBOO Type K pipe clamp, −40 to 200 °C (-40 to 392 °F), with adapter

A clamp that carries Klein's part number in its own title and claims double the original's range for half the price.

ZIBOO type K pipe temperature clamp with banana plug adapter

ZIBOO Type K pipe clamp, −40 to 200 °C (-40 to 392 °F), with adapter

A clamp that carries Klein's part number in its own title and claims double the original's range for half the price.

Type and plug fit: Type K, stated, and the BANANA PLUG ADAPTER IS INCLUDED — which is the genuine advantage over the Klein 69140, where the adapter is Cat. No. 69146 and sold separately. ZIBOO then notes that the adapter is "also sold separately (Cat. No. 69146)", quoting Klein's catalog number for a part it has put in its own box
Probe style: A PIPE CLAMP, closing round pipes from 1/4 to 1 1/2 inch — an eighth of an inch more than the Klein 69140 claims. Like that clamp, it is a style this shelf's introduction does not name among its bead, pad and rod
Stated temperature range: −40 to 392 °F (−40 to 200 °C), claimed. The Klein 69140, whose part number is in this product's title, states −4 to 212 °F (−20 to 100 °C). That is NEARLY TWICE the span, and twice the ceiling, on a copy that costs $14.99 against $26.98. Nothing on either page explains the difference, and a clamp reading 200 °C (392 °F) would reach a hot gas discharge line the original cannot
Stated accuracy: ±2%, the same figure the Klein 69140 gives, followed by the same sentence: "Thermocouple accuracy is dependent on the accuracy of the meter being used." The wording of this listing follows the Klein listing bullet for bullet — wide temperature range, versatile pipe clamp, flexible lead, universal compatibility, dependable accuracy — in the same order
Cable length: 39.78 inches, 102 cm, flexible. The Klein 69140 states 40 inches for the same 102 cm (40.2 in). Thirty-nine point seven eight inches is 101.04 cm (39.8 in), so the figure has been converted from the metric and given to two decimals rather than measured
Clamp capacity: Pipes 1/4 to 1 1/2 inch, then "(up to 35 cm (13.8 in))" — the same parenthesis that appears on the Klein page, where it is equally wrong. One and a half inches is 38 Millimeters. Thirty-five centimeters is not a pipe this clamp or any other on this shelf would close around
Also stated: The reference field reads 69028+69146 — two Klein Tools catalog numbers concatenated, 69146 being the banana adapter. The title opens "ZIBOO 69140 K-Type Thermometer", and 69140 is the Klein part number of the clamp sitting next to it in this same relevé. The brand on the box is ZIBOO; the part numbers on the listing are all somebody else's

The part number in the title belongs to the clamp next to it

69140 is Klein Tools.

The genuine Klein 69140 is on this shelf under its own name, at $26.98.

The reference field here reads 69028+69146 — two more Klein catalog numbers, 69146 being the banana adapter.

The brand on the box is ZIBOO. Every part number on the listing is somebody else’s.

And the copy claims twice the range of the original

Klein 69140: −4 to 212 °F. Minus twenty to a hundred Celsius.

This: −40 to 392 °F. Minus forty to two hundred.

Twice the ceiling, twice the span, twelve dollars cheaper, under the same number.

A type K junction is good to well past 1000 °C (1832 °F) — the Nxtop probe on this shelf states 1100 for $8.99 — so what limits a clamp is the spring, the insulation and the lead, and a 200 °C (392 °F) clamp is buildable.

Nothing on this page says the figure was measured.

Bullet for bullet, in the same order

Klein: wide temperature range · versatile pipe clamp · flexible lead · universal compatibility · dependable accuracy.

ZIBOO: wide temperature range · versatile pipe clamp · flexible lead · universal compatibility · dependable accuracy · included banana plug adapter · optional adapter available.

Including the same closing caveat, word for word: thermocouple accuracy is dependent on the accuracy of the meter being used.

And including “(up to 35 cm (13.8 in))” after a pipe diameter in inches, which is wrong on both pages — an inch and a half is 38 millimeters.

What it genuinely does better

The adapter is in the box.

“The miniature flat plug that connects it is where fit fails.”

A thermocouple plug does not fit a meter’s 4 mm (0.16 in) sockets. The Klein needs Cat. No. 69146 ordered separately. This one arrives connectable.

Thirty-nine point seven eight inches of lead, which is 101.04 cm (39.8 in) — the metric figure converted to two decimals rather than measured, but the same meter of cable as the original.

What gets asked here

Is this a Klein 69140?

No. The brand is ZIBOO and the Amazon reference is its own; what it carries is Klein's part NUMBER, in its title and in its reference field, where 69028+69146 are two further Klein catalog numbers. The genuine Klein 69140 is on this shelf under its own name at $26.98. Borrowing a part number is how a compatible accessory tells you what it stands in for — the YUNFOOK fuse on the multimeter-fuses shelf does the same thing with part 803293. The difference here is that the number names a product this site also reviews, with a different specification.

Can it really read to 200 °C (392 °F) when the part it names stops at 100 °C (212 °F)?

Possibly, and that is not the same as verified. A type K thermocouple junction is good to well over 1000 °C (1832 °F) — the Nxtop probe on this shelf states 1100 °C (2012 °F) for $8.99. What limits a pipe clamp is the spring, the insulation and the lead, not the junction. So a 200 °C (392 °F) clamp is entirely buildable. What this page does not give is any reason to believe the figure was measured rather than chosen, and the only comparison available is the original's own 100 °C (212 °F). If the reading matters above 100 °C (212 °F), verify against a second probe.

What does the included adapter save me?

An order and a wait. A thermocouple plug does not fit a multimeter's 4 mm (0.16 in) banana sockets, and the part that bridges them is Klein's Cat. No. 69146 — which this listing both includes and names as separately available. This shelf's introduction is explicit that the plug is where fit fails, so a clamp that arrives able to connect to the meter you own is worth more than its price difference suggests. Check which socket your meter has first: a dedicated thermocouple input needs no adapter at all.

Instruments this fits

More temperature probes

Fieldpiece Dual type K thermometer, T1, T2 and T1−T2

A two-channel delta-T instrument with its own beaded probes, and the only thing on this shelf you can calibrate.

Type and plug fit
TWO type K channels, with "wrap tab beaded thermocouples" included. Fieldpiece lists an optional ATWB1 wet bulb thermocouple as a further accessory. An LED indicates a DISENGAGED PROBE — a plug that has worked loose — which is the only answer on this shelf to the problem this shelf's introduction raises about plugs, approached from the instrument end rather than the probe end
Probe style
WRAP-TAB BEADED, supplied. A bead is the fast-response style this shelf's introduction assigns to air, and a wrap tab lets the same bead be strapped to a pipe or a fin. Two of them, because the instrument exists to read a difference
Stated temperature range
−58 to 2000 °F (−50 to 1300 °C), stated. That is the widest span on this shelf by a long way — 1350 Celsius degrees, against 1100 for the Nxtop probe, 480 for the Klein 69142 and 100 for the Klein 69140 clamp. It is the instrument's range; what any given reading can reach depends on the thermocouple fitted, and the supplied beads are not 1300 °C (2372 °F) parts
Stated accuracy
NOT PUBLISHED. What is published instead is more unusual: TWO FRONT-FACE CALIBRATION POTS, one per channel. This is the only instrument on this shelf that can be adjusted by its owner, which is a different proposition from a stated tolerance — it means the reading can be matched to a reference rather than trusted as supplied
Functions
Reads T1, T2 or T1−T2, with the difference "in big numbers on the LCD". Min/Max and Hold. Fieldpiece states "great temperature compensation for fast changing environments", which is the figure a two-channel meter lives or dies by and is given here as a claim rather than a number
Cable length
Not stated for the supplied thermocouples. No length is published for either of the two thermocouples it ships — the one figure of the hub’s five that this page omits
Construction and safety
A rugged rubber boot, and a clear-front case with the ANC6 magnetic hanger included. A magnetic hanger on an HVAC job is not a nicety: it puts the meter on the side of the unit at eye level while both hands are in the cabinet
Also stated
386 grams — five times the 78 g (2.8 oz) of the Nxtop, the next heaviest probe here. At $119 it is also the most expensive, and it is a different kind of purchase from the rest of the shelf: four of these five products are probes for a meter you already own, and this one is the meter

Klein Tools Type K pipe clamp, −20 to 100 °C (-4 to 212 °F)

The genuine Klein pipe clamp — and the narrowest temperature range on this shelf, at the highest price of the two clamps.

Type and plug fit
Type K, stated. "Works with any digital multimeter or clamp meter that measures temperature", and Klein adds that its K-type accessories work with all Klein multimeters and clamp meters that measure temperature "as well as any other brand with meters that measure temperature". The banana plug adapter is NOT in the box: it is Cat. No. 69146, sold separately — which matters because this shelf's introduction says the plug is where fit fails
Probe style
A PIPE CLAMP, which is a fourth style this shelf's introduction does not name. It lists a bead for air, a flat pad for surfaces and a sheathed rod for immersion; a spring clamp that closes round a pipe reads the outside wall of a line you cannot immerse anything in. It is the dominant style in the American relevé for this shelf, because that is how a refrigeration circuit is diagnosed
Stated temperature range
−4 to 212 °F (−20 to 100 °C), stated. That is the NARROWEST range on this shelf: the published Taiss states −40 to 350 °C (-40 to 662 °F), the Nxtop 0 to 1100 °C (32 to 2012 °F), the Klein 69142 beside it 0 to 480 °C (32 to 896 °F), and the ZIBOO clamp that borrows this part number claims −40 to 200 °C (-40 to 392 °F). One hundred degrees Celsius is the top of it, which covers a heating flow and stops below a hot gas line
Stated accuracy
±2%, stated — and then the sentence that makes it honest: "Thermocouple accuracy is dependent on the accuracy of the meter being used." Two probes on this shelf publish a figure at all — this clamp and the ZIBOO — and both add that caveat. It is the right way to put it: a thermocouple generates a voltage, and what turns that voltage into a number is the instrument
Cable length
40 inches, 102 cm, flexible. The ZIBOO clamp states 39.78 inches for the same 102 cm (40.2 in), which is the same lead described to two decimal places. The published Taiss five-pack gives 3 m (10 ft), three times either clamp
Clamp capacity
Pipes from 1/4 to 1-3/8 inch diameter. The ZIBOO clamp claims 1/4 to 1 1/2 inch — an eighth of an inch more. Both listings then add "up to 35 cm (13.8 in)", which is not a pipe diameter at all and appears on both pages
Heat resistance
Not stated separately from the measuring range. Klein positions this as the accessory that "extend[s] working temperature ranges for Klein's HVAC Digital Multimeters and Clamp Meters", and names the rest of the family: high temperature thermocouple wire, temperature probe and banana plug adapter

Klein Tools High-temperature type K thermocouple, 0 to 480 °C (32 to 896 °F)

Klein's high-temperature thermocouple — 480 °C (896 °F), a coiled lead, and no stated accuracy or probe style.

Type and plug fit
Type K, stated, and the ADAPTER IS INCLUDED — "with Adapter" is in the product title. That puts it with the ZIBOO clamp and against the Klein 69140, where the adapter is a separate part number. "Works with any digital multimeter or clamp meter that measures temperature"
Stated temperature range
32 to 896 °F (0 to 480 °C), stated. Nearly FIVE TIMES the ceiling of Klein's own 69140 pipe clamp, which stops at 100 °C (212 °F) — and Klein says so directly: these accessories "extend working temperature ranges for Klein's HVAC Digital Multimeters and Clamp Meters". It does not go below freezing, which the two pipe clamps on this shelf both do
Probe style
NOT STATED. This shelf's introduction makes probe style the thing you choose by the job — a bead for air, a flat pad for surfaces, a sheathed rod for immersion — and this listing says only "High Temperature Thermocouple". There is no bead, no pad, no sheath and no tip dimension anywhere on the page, which is the one specification a buyer needs to know whether it will sit on a flue or in it
Stated accuracy
NOT PUBLISHED. The listing gives only the caveat without the figure: "Accuracy of the thermocouple is dependent on the accuracy of the meter being used." Both pipe clamps on this shelf state ±2% alongside that sentence; this one states the sentence alone, at the highest price of the three Klein parts
Cable length
A COILED lead, 3 feet — the only coiled lead on this shelf, and shorter than either pipe clamp’s meter. Coiled matters on a hot job: a straight lead draped across a flue collects heat along its length, while a coil keeps the cable off the work and pulls back out of the way
Heat resistance
Implied by the 480 °C (896 °F) measuring range and not stated separately for the lead. Klein lists "High Temperature Thermocouple Wire" as a DIFFERENT accessory in the same family, which suggests the wire on this part is not itself the high-temperature item
Also stated
11 grams, the lightest probe weight published on this shelf. Klein names the rest of the K-type family on this page — temperature pipe clamp, temperature probe, high temperature thermocouple wire and banana plug adapter — which is the clearest accessory map any maker on this shelf publishes

Linkhood Back probe kit, 31 pieces, 30 V

A kit built entirely around reading a connector from behind, rated 30 volts — the lowest on this shelf by a factor of thirty.

Stated rating
TWO RATINGS ON ONE PAGE. The back probes are stated for "testing up to 30 Volts for Connectors, Automotive Sensors and Fuel Injectors", and the alligator clips separately as "CATII 300Vac/15A". The description then gives "Rated Voltage: 30V" for the kit. Thirty volts is the LOWEST figure on this shelf by a factor of thirty, and it is the right one to believe: a kit is rated by its weakest part, and these are 0.07 mm (0.003 in) needles
Insulation
SOFT PVC, stated — "Cable Material: Soft PVC". It is the ONLY product on this shelf whose insulation is named as PVC, and this shelf's introduction says in so many words that silicone "stays flexible in the cold where PVC goes stiff and cracks". Five sets on this shelf name silicone; the three Klein sets name nothing; this one names the material the hub warns about
Probes and angles
15 BACK PROBE PINS in stainless steel, at THREE angles — 90°, 135° and straight — in five colors, with 0.07 mm (0.003 in) needle tips. Three angles is the specification that makes the kit: a connector you can reach from directly behind takes a straight pin, one in a loom against a bulkhead takes 90°, and 135° is for everything in between. No other product on this shelf offers an angle at all
Plugs and tips
4 mm (0.16 in) banana plugs, stated. Five banana-plug-to-alligator-clip leads, five WIRE PIERCING PROBES that connect to the banana leads, and five nickel-plated copper alligator clips with a maximum jaw opening of 15 mm (0.59 in). The piercing probes work through a white plastic case: the wire goes in the case and the probe pierces it, which keeps the pierced spot located and the needle supported
Length
39.37 inches, 1 meter, for each of the FIVE leads. Five leads rather than two is unusual on this shelf and it is deliberate: diagnosing a sensor often means holding a reference, a signal and a ground at once, across two instruments
Supplied
31 pieces: 15 back probe pins, 5 banana-to-clip leads, 5 wire piercing probes, 5 alligator clips, and a storage box. 230 grams, $20.37. Stated for "Automotive Diagnostics, Testing, and Repairing, but also used in Physics Laboratories, Service Shops, Schools, Homes, and Industries"

PUKAIBUL Silicone lead kit, 125 cm (49.2 in), CAT III 1000 V

The longest lead on this shelf and the cheapest published CAT III rating here, at ten dollars.

Stated rating
CAT III 1000 V 20 A, stated twice on the page. At $9.99 that makes it the CHEAPEST published CAT III rating on this shelf — a third of the Fluke, which names no category, and half the Klein pairs, which reach CAT IV. This shelf's introduction makes the stated rating the first comparison, and the three European sets on this shelf publish none
Insulation
SILICONE, stated, "soft insulation remains flexible and helps reduce tangling during use". No temperature figures are given — the Eiranoly is the only product on this shelf that publishes an operating range. Silicone is the material this shelf's introduction prefers, against PVC that stiffens and cracks in cold
Length
49 inches, 125 cm, stated — the LONGEST single lead on this shelf. The published PeakTech is 120 cm (47.2 in), the Klein 69410,104 cm, the Bionso 109 cm (42.9 in) and the two other Klein sets 91 cm (35.8 in). Only the Klein 69483 reaches further, and only by screwing a three-foot extender onto a three-foot lead
Plugs and tips
Standard 4 mm (0.16 in) banana jacks, with GOLD-PLATED sharp probe tips built into the leads. The kit adds two extended 2 mm (0.08 in) needle probes and two non-destructive PIERCING PROBES with 0.7 mm (0.03 in) needle tips, which push through insulation to read a conductor without stripping it. Four protective caps. The plugs are not described as shrouded
Supplied
Two 49-inch leads with built-in probes, two piercing probes with 4 mm (0.16 in) banana jacks, two 2 mm (0.08 in) extended needle probes, two alligator clips, four caps and a transparent case — ten pieces for $9.99. 180 grams. Stated to fit "most digital multimeters including Fluke, AstroAI, and Klein"
Also stated
The listing's first bullet carries a stray closing quotation mark, and the kit's name appears three different ways across the page ("meter leads", "multimeter leads kit", "replacement multimeter probes"). The specification itself is consistent: 49 inches, CAT III 1000 V, 20 A, silicone, 0.7 mm (0.03 in) piercing needles, 2 mm (0.08 in) needle probes
