Extech TM100 Type K/J Single Input Thermometer

This instrument supports either a Type K or Type J thermocouple probe (one channel only) and provides impressive measurement ranges: for Type K probes, about –200 °C to +1372 °C (–328 °F to +2501 °F); and for Type J probes, about –210 °C to +1100 °C (–346 °F to +2012 °F).The device features high resolution (selectable 0.1° or 1° increment) and a large back‑lit LCD screen that allows readings in °C, °F or Kelvin.It supports standard functions like data‑hold (freeze the reading), Min/Max/Avg tracking (with relative time stamp), offset (zero) key for relative measurements, and automatic power‑off (with option to disable).It includes a Type K bead wire probe and a 9 V battery, ready for use out of box. The form‑factor is compact (~220 × 63 × 28 mm / 8.7″ × 2.5″ × 1.1″) and light (~200g) for handheld one‑hand operation. It is particularly well‑suited to tasks like equipment monitoring, process temperature verification, furnace or high‑temperature testing, as well as general lab or field use where a single thermocouple channel is sufficient.

Features

• Wide measurement range: Type K: approximately –200 °C to +1372 °C (–328 °F to +2501 °F); Type J: approximately –210 °C to +1100 °C (–346 °F to +2012 °F).

• High resolution: switchable 0.1° or 1° increments.

• Large back‑lit LCD display: allows visibility in low‑light environments and supports °C, °F, Kelvin units.

• Data‑hold, Min/Max/Avg functions with relative time stamp: freeze a reading, or review extremes and averages across a measurement session.

• Offset (zero) key: Enables relative measurement mode where you can subtract a baseline value to record differences.

• Auto power‑off to conserve battery (with a disable option for continuous use).

Includes

•  Type K bead wire temperature probe
• (3) AAA 1.5V batteries
