PUKAIBUL silicone multimeter test lead kit with needle probes and piercing pins

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

The longest lead on this shelf

A hundred and twenty-five centimeters.

Published PeakTech: 120. Klein 69410: 104. Bionso: 109. Both other Klein sets: 91.

Only the Klein 69483 goes further, and only by screwing a three-foot extender onto a three-foot lead for fifty dollars.

What the extra reach buys is the meter on the floor of a car while the probes are under the dashboard.

Ten dollars with the category printed

CAT III 1000 V, 20 A, stated twice.

The three European sets on this shelf publish no category. The Fluke at $33.83 publishes none. The twenty-five-piece Bionso at $29.99 publishes none.

This is the cheapest published CAT III on this shelf by a factor of two.

Publishing a rating and holding one are different things, and only the first is visible from a listing. Read what is printed on the lead body.

Piercing probes, and what they cost you

Nought point seven of a millimeter, through the insulation, onto the conductor. No stripping, no cutting.

It is standard practice on a loom and it is not free: a hole in the insulation of a signal wire is fine in a dry cabin and a slow corrosion site in a wheel arch.

Use them where a connector cannot be back-probed. Seal the hole afterwards.

The Linkhood kit on this shelf exists to avoid exactly this, with fifteen back probes instead.

And two kinds of needle

Two extended 2 mm (0.08 in) needle probes for a point you can reach.

Two 0.7 mm (0.03 in) piercing needles for a wire you cannot.

Plus the built-in sharp tips on the leads themselves, gold plated, and four caps for them.

What ten dollars leaves out

No wear indication. No adjustable shroud. No bend count. No operating temperature range. No wire gauge.

No CAT IV, where the three Klein sets on this shelf reach it.

And a first bullet that ends with a quotation mark nobody opened.

What gets asked here

Does length cost you anything?

Almost nothing you will notice, and it buys a great deal. On voltage and continuity the extra lead adds a fraction of an ohm in series with a circuit of thousands, and a meter's input impedance makes it irrelevant. On low-ohms work — a winding of a few ohms — it matters, and the fix is thirty seconds: short the probes together, note the reading, subtract it, or use the meter's relative function. What 125 cm (49.2 in) buys is a meter on the floor of a car while the probes are under the dashboard, which no 91 cm (35.8 in) lead will do.

Is a piercing probe safe on a car loom?

It is standard practice and it is not free. A 0.7 mm (0.03 in) needle through the insulation of a signal wire leaves a hole in the insulation of a signal wire — fine in a dry cabin, a slow corrosion site in a wheel arch or an engine bay. Use them where you cannot back-probe a connector, seal the hole afterwards, and prefer the back probe route when a connector is accessible. The Linkhood kit on this shelf is built entirely around back probes for that reason.

How can ten dollars buy a CAT III 1000 V rating when thirty-four does not?

Because publishing a rating and holding one are different things, and only the first is visible to a buyer. This listing states CAT III 1000 V 20 A; the Fluke TL175 at $33.83 states no category at all while describing patented safety features in detail. Neither page shows a test report. What the ten-dollar set does not have is a wear-indicating second layer, an adjustable shroud, a thirty-thousand-bend figure, or a maker whose reputation is staked on instruments. Read what is printed on the lead body, and follow the instructions supplied with your instrument.

Bionso 25-piece probe kit with threaded tips

Five tip sizes, two hooks, two back probes and a wrench to swap them — and not a single rating figure on the page.

Stated rating
NO CATEGORY AND NO VOLTAGE PUBLISHED. Twenty-five pieces, $29.99, five bullets of specification, and not one figure for category, voltage or current. It is one of five sets on this shelf that publish no category at all, with the Fluke TL175, the AUTOOL kit, the KAIWEETS set and the PeakTech pair. This shelf's introduction makes stated ratings the first of its five comparisons, and the published PeakTech fiche on this shelf says a rating should be in the listing
Insulation
SILICONE, "cold and high temperature resistant, very soft, more flexible use", double insulated, with "100 high-purity copper wire" — a phrase that is presumably meant to read 100 per cent. No temperature figures and no gauge. Silicone is the material this shelf's introduction prefers over PVC
Plugs and tips
REPLACEABLE gold-plated probes in five sizes: four at 1.0 mm (0.04 in), two at 2.0 mm (0.08 in), two 3.8 mm (0.15 in) banana plug probes and two 0.7 mm (0.03 in) back probe pins, plus two test HOOKS that clip onto a component leg and stay there. Two TIP SHROUDS are included — cover for the exposed metal, which only the Fluke otherwise addresses on this shelf, and here as a separate part rather than an adjustable sleeve
Length
43 inches, 109 cm, for the two leads. Mid-length on this shelf: under the PUKAIBUL's 125 cm (49.2 in) and the published PeakTech's 120 cm (47.2 in), over the Klein 69410's 104 cm (40.9 in)
Supplied
Two 43-inch leads, two handles, four 1.0 mm (0.04 in) probes, two 2.0 mm (0.08 in) probes, two 3.8 mm (0.15 in) banana plug probes, two 0.7 mm (0.03 in) back probe pins, two alligator clips, two tip shrouds, ONE WRENCH, two test hooks and two storage boxes. Twenty-five pieces. The wrench is the only tool supplied with anything on this shelf, and it exists because threaded tips have to be nipped up rather than finger-tight. 210 grams
Also stated
A three-month refund and a two-year warranty, both stated. Bionso claims the kit "works perfectly with any multimeter, clamp meter or test instrument", which is a compatibility claim and not a rating. Compared with the published AUTOOL set on this shelf, which runs to 68 pieces, this is the smaller of the two big kits

Eiranoly Silicone lead pair, CAT II 1000 V, 103 cm (40.6 in)

The cheapest set on this shelf, the only one that publishes a temperature range — and the only CAT II leads with a 1000 V figure beside it.

Stated rating
CAT II 1000 V, 20 A, stated. That is the point to read carefully, because the buying tip on the multimeter shelf of this site puts it exactly: the category and the voltage are one specification, not two, and the higher-looking number is not the safer tool. CAT II 1000 V is a LOWER category than the CAT III 1000 V of the PUKAIBUL at $9.99 and the CAT III 1000 V / CAT IV 600 V of the three Klein sets — and fitting these to a CAT III meter gives you, per this shelf's introduction, a CAT II pairing
Insulation
DOUBLE-INSULATED SILICONE, with the only OPERATING TEMPERATURE RANGE published anywhere on this shelf: −58 °F to +392 °F, −50 °C to +200 °C (392 °F). This shelf's introduction compares silicone against PVC for cold flexibility and no other listing here puts a number on it — the Fluke says "remain flexible in cold temperatures" without one
Length
40.5 inches, 103 cm, stated. Mid-length for this shelf: shorter than the PUKAIBUL's 125 cm (49.2 in) and the published PeakTech's 120 cm (47.2 in), a centimeter under the Klein 69410's 104 cm (40.9 in), longer than the 91 cm (35.8 in) of the two other Klein sets
Plugs and tips
Gold-plated ULTRA-SHARP probes, stated to pierce wire insulation or reach a solder joint on a dense board, and "a universal 4.2mm (0.17 in)(0.16inch) banana plug". Two figures that do not agree: 0.16 inch is 4.06 mm (0.16 in), and the standard every other listing on this shelf names is 4 mm (0.16 in). A plug genuinely 4.2 mm (0.17 in) across would be a tight fit in a 4 mm (0.16 in) socket; the likeliest reading is that this is a standard 4 mm (0.16 in) plug described loosely
Supplied
One red lead, one black lead, one red clip, one black clip and FOUR probe safety covers — two more than needed, and the listing explains why: "customers have reported that they are easily lost, so we've included 2 extra probe covers". That is the only listing on this shelf that changed its contents because of what buyers said. 77 grams, the lightest set on this shelf
Also stated
Compatible with "almost all mainstream brands of multimeters and clamp meters such as Fluke, AstroAI, INNOVA, Klein Tools". Stated to be tangle-resistant and stretch-resistant. At $6.79 it is the cheapest item on this shelf

AdirPro Grade rod, 14 ft, 4 sections, 1 mm (0.04 in) wall

Fourteen feet on four sections and the thickest wall on the shelf — on a page that cannot agree with itself about the graduation.

Body and fittings
FOUR telescopic sections reaching 14 ft and collapsing to 51 in. Four sections for fourteen feet is the best length-per-joint ratio on this shelf — three and a half feet per section — against five sections for nine feet on another AdirPro here. Each joint is a creep point, so fewer is stiffer
Material
1 mm (0.04 in) thick, ± 0.05 mm (0.002 in), stated. It is the THICKEST published wall on this shelf — the only other figure given is 0.8 mm (0.03 in) — and on a 14 ft rod extended to its limit, wall thickness is what stops the top section bowing under its own weight
Scale
The TITLE says "10th Foot Graduations". The fourth bullet says "dual graduations of an engineer's scale feet/eights on the front and standard feet/inches on the back". Tenths and eighths are not the same scale and they are not interchangeable: an engineer's level is set out in tenths, and reading an eighths rod against it means converting every figure. Settle this on the order page
Stated dimension or range
14 ft extended, 51 in folded — both published, which only two rods on this shelf manage
Measuring mode
A bubble level, stated, and a rectangular section stated to ensure easy handling and flush alignment with flat surfaces. A special measuring scale on the back for overall height reading is stated without being explained
Supplied
A durable soft carrying bag with an adjustable shoulder strap. No spare lock button, unlike the maker's own 9 ft rod on this shelf, and nothing is published about the locking buttons at all

AdirPro Grade rod, 9 ft, 5 sections, 8ths

The only rod on this shelf that ships a spare for the part that actually fails.

Supplied
A REPLACEMENT LOCK BUTTON is included in the package, stated — the only spare part supplied with any rod on this shelf. This shelf's buying tip says to check that every section locks positively, because a staff whose middle section creeps adds an error you will not notice in the numbers; the lock button is that part, and it is a small sprung plastic component that breaks. A carrying bag is included as well
Body and fittings
LARGE locking buttons, stated to lock the sections securely and prevent slippage. Five telescopic sections in thick aluminum alloy and plastic, stated 100% waterproof and corrosion-resistant — the only rod here to claim waterproof rather than weather-resistant
Stated dimension or range
9 ft extended on five sections. No folded length is published, which on a five-section 9 ft rod would be about two feet. One rod on this shelf reaches 14 ft on four sections
Scale
Red foot markings for maximum visibility, stated ideal for use with construction lasers and optical surveying equipment, with a backside scale for overall height reading measured in 8ths. Eighths rather than tenths: eighths read naturally against a tape and tenths against an engineer scale, and the two are not interchangeable
Material
Thick aluminum alloy and plastic, stated. No thickness figure appears, where two rods on this shelf publish one
Reference and mounting
A rectangular section, stated to give an easy grip while taking measurements. No tripod thread and no receiver clamp is published
