Handheld Type K/J thermocouple thermometer with wide range, 0.1° resolution, backlit LCD in °C/°F/K, and Hold / Max / Min / Avg with relative time stamp.
Key advantages
- Wide Type K range — −200…1372 °C (−328…2501 °F); Type J −210…1100 °C (−346…2012 °F).
- ±0.15% of reading + 1 °C — (±0.15% + 1.8 °F); 0.1 °F/°C max resolution.
- Backlit LCD — °C / °F / K; data Hold; Max/Min/Avg with relative time stamp; offset/zero for relative measurements.
- Ready kit — includes Type K bead-wire probe and batteries; auto-power-off with disable.
Typical applications
- General process and HVAC temperature checks with Type K or J probes.
- Field measurements needing one-hand side-button controls and relative offset.
Selection guide
- Inputs — Single Type K/J thermocouple input.
- Accuracy / resolution — ±0.15% of reading + 1 °C / 1.8 °F; 0.1° max resolution.
- Display — Large backlit LCD; Hold; Max/Min/Avg with time stamp.
- Power — Three AAA 1.5 V batteries (per extech.com product page).
- Included — Type K bead wire probe; batteries.
- Approvals — CE (per datasheet notes).
Common mistakes
- Expecting dual-channel logging — TM100 is a single-input thermometer.
- Using a Type T/E probe without confirming input support — published as Type K/J.
- Relying on bead-wire probe accuracy at high temperature without a suitable probe.
- Test & measurement
When to RFQ / what to tell us
- Type K vs J probes needed beyond the included bead wire.
- Temperature range of interest; quantity; ship-to country.

FAQ
Q: Does it include a probe? A: Yes — a Type K bead-wire probe ships with the meter. Order process probes separately if needed.
Q: Type T supported? A: Published inputs are Type K and Type J only.
Q: What should I send for a quote? A: Probe needs, quantity, ship-to. Compatible with systems using Extech TM100 if you need a drop-in check — we do not claim authorized-dealer status.
