A type K thermocouple thermometer with probe, described as offering high-precision temperature detection. A wide range of operating temperatures, with the instrument built from stated quality materials. Digital display.
Why a separate thermometer earns its place
Temperature is the measurement that takes time. A circuit voltage is read in a second; a flow temperature settling, a bearing warming up or a wall drying out is watched over minutes or hours. Tying up the multimeter for that is what stops it happening.
What is not published
No accuracy figure and no stated range in this listing. Both are in the documentation, and both matter more here than the display size.
Availability
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

What gets asked here
Why not just use a multimeter with a temperature range?
Because a temperature measurement often has to run while other measurements are being taken. A dedicated thermometer can be clipped on and left, which a shared multimeter cannot.
What accuracy does it state?
None appears in the listing. It states high-precision detection without a figure, which is the pattern across most of this category.
Can I use other probes with it?
It is stated as a type K instrument, so any type K probe with the matching miniature plug should read on it.
The cheapest probe on this shelf, the hottest, and the only one that publishes a dimension for its plug.
Type and plug fit
Type K with a MINIATURE K-TYPE CONNECTOR, and the fork terminal spacing is published: 5 mm (0.20 in), 0.197 inch. It is the ONLY probe on this shelf that gives a dimension for its plug, and this shelf's introduction says in so many words that "the miniature flat plug that connects it is where fit fails". A nine-dollar probe answers the shelf's stated failure point, and the twenty-seven and thirty-dollar Kleins do not
Probe style
A SHEATHED ROD, 3 mm (0.12 in) diameter by 200 mm (7.87 in) long — the immersion style this shelf's introduction names. Total length 29.5 cm (11.6 in) with the cable gland, so roughly 9 cm (3.5 in) of that is body rather than probe. It is the only product on this shelf whose probe geometry is fully dimensioned
Stated temperature range
0 to 1100 °C (32 to 2012 °F), stated. That is the HIGHEST range published by any probe on this shelf: the Klein 69142 reaches 480 °C (896 °F), the published Taiss 350 °C (662 °F), the ZIBOO clamp 200 °C (392 °F) and the Klein 69140 clamp 100 °C (212 °F). Only the Fieldpiece ST4 meter claims more, at 1300 °C (2372 °F), and that is the instrument's range rather than a probe's. Like the Klein 69142 it does not go below zero
Cable length
30 cm (11.8 in), 12 inches, stated "not stretched" — the SHORTEST on this shelf by a wide margin. The two pipe clamps give 102 cm (40.2 in), the Klein 69142 three feet, the published Taiss 3 m (10 ft). Thirty centimeters puts your hand about a foot from whatever is at 1100 degrees, which is the real limit of this probe and has nothing to do with its sensor
Stated accuracy
NOT PUBLISHED, and no tolerance class is named either. Only the two pipe clamps on this shelf publish a percentage at all; this one publishes nothing. At $8.99 that is the trade being offered, and the sentence both Klein clamps print applies here too whether or not it is written: what turns the junction voltage into a number is your meter
Heat resistance
Implied by the 1100 °C (2012 °F) range for the sheath, and unstated for the cable. The listing describes the materials only as "Electronic Parts, Plastic" and the color as yellow, which is the standard color coding for type K in American practice. A plastic-insulated 30 cm (11.8 in) lead is what sets the working distance, not the stainless rod
Also stated
78 grams, against 11 g (0.4 oz) for the Klein 69142. The listing is written as a parts-catalog entry rather than marketing — product name, model, type, color, material, range, weight, fork spacing, probe dimensions, total length, cable length, package contents — and that is why it publishes more dimensions than anything else on this shelf

Eleven hundred degrees for nine dollars
The only plug dimension published on this shelf — 5 mm (0.20 in)
Thirty centimeters of cable, at 1100 degrees
Best for: Kiln, furnace, forge and flue work, where 1100 °C (2012 °F) is the specification and a 30 cm (11.8 in) cable is enough
Leads with three swappable ends, so one set covers a terminal, a component leg and a wire you cannot hold — in cable stated to stay flexible in the cold.

Construction and safety
Three interchangeable connectors · double-insulated · flexible at low temperature
Three interchangeable connectors: crocodile clips, needle probes and mini clamps
Double-insulated material, stated as staying soft and elastic at low temperatures
No measurement category or voltage published
Best for: Bench and vehicle work where the third hand is the problem.
A clip-only lead in 18 AWG — the one set here that tells you the size of the wire inside it.
Stated rating
CAT III 1000 V / CAT IV 600 V, stated. The same pairing as the two other Klein sets, and the three of them are the only CAT IV items on this shelf. This shelf's introduction explains the arithmetic: the rated pair is the lower of meter and leads
Insulation
18 AWG DOUBLE INSULATED WIRE, stated — and the gauge is what makes this listing unusual. No other product on this shelf publishes a wire gauge at all. What it does NOT say is the material: not silicone, not PVC, just double insulated, as on both other Klein sets
Plugs and tips
Banana plug at one end, HEAVY-DUTY ALLIGATOR CLIP at the other, right-angle at the plug. There is no probe tip: this is a clip-only lead, which is a different purchase from the 69410 beside it where the clips unscrew. No shrouding is mentioned
Length
3 feet, 91 cm — the shortest of the three Klein sets and the shortest stated lead on this shelf. Against the PUKAIBUL's 125 cm (49.2 in) and the published PeakTech's 120 cm (47.2 in), that is a third less reach
Stated application
INSULATION RESISTANCE TESTING, named in a bullet as "a perfect application for heavy-duty leads". That is a specific and sensible claim: an insulation test applies hundreds of volts between a conductor and earth for a minute at a time, which is a job for a clip that stays put rather than a probe held by hand
Supplied
One pair of universal right-angle leads with heavy-duty clips. The clips are not described as removable, which is the trade against the 69410: more clip, less versatility, same price to within two cents — $19.99 against $19.97

Eighteen AWG published, alone on this shelf
CAT III 1000 V and CAT IV 600 V
Clips only — there is no probe tip
Best for: Insulation resistance testing and any reading you need to leave clipped on while you work
A plain rated pair — and the rating is the whole point, because the three European sets on this shelf publish none.
Stated rating
CATEGORY III 1000 V AND CATEGORY IV 600 V, stated in a bullet. This shelf's introduction is explicit about why that matters: "fitting unrated leads to a CAT III meter gives you a CAT III meter with unrated leads, and the manufacturer's rating for the pair is the lower of the two". The three European sets previously on this shelf publish no category at all; this is one of three sets here that reach CAT IV
Insulation
NOT NAMED. The listing says the leads are durable and says nothing about silicone or PVC — and this shelf's introduction makes that comparison one of its five: silicone stays flexible in the cold where PVC goes stiff and cracks. All three Klein sets share the omission, which is odd on a product whose own description stresses that it is designed by electricians for electricians
Plugs and tips
Right-angle, "standard banana-type inputs compatible with most multimeters and clamp meters". No tip length is published and the plugs are not described as shrouded. A right-angle plug is the detail that keeps a meter from being levered off a ledge by its own leads, and it is why these fit Klein's own lead storage compartments
Length
41 inches, 104 cm, stated. That sits below the published PeakTech's 120 cm (47.2 in) and well below the PUKAIBUL's 125 cm (49.2 in) on this shelf, and above the 3 ft (91 cm) of the two other Klein sets
Supplied
One pair of universal test leads and one set of REMOVABLE alligator clips. Removable is the useful word: the clips come off, so one purchase covers a probe measurement and a hands-free one. 91 grams
Also stated
The leads "are compatible with and fit the lead storage compartment on most Klein test and measurement products" — which is a specification about the METER rather than the lead, and the only one of its kind on this shelf. Klein also offers insulation resistance testing as an application of its heavy-duty sibling, the 69381
