Type K/J Thermometer


Extech TM100: Type K/J Single Input Thermometer

Compact-size Thermometer with Side-Button Controls For Convenient One-hand Operation

The Extech TM100 Type J/K Single Input Thermometer has a wide temperature range of -328 to 2501°F/-200 to 1372°C for type k and -346 to 2012°F / -210 to 1100°C for type j measurements. It has a high 0.1°/1° resolution and a large backlit LCD display with readouts in °F, °C, or Kelvin. The data hold function freezes the reading on the display and the screen displays the Max/Min/Avg. Readings capture a relative time stamp. Also, the offset key is used for zero function to make relative measurements. Auto power off with a disable feature. This thermometer comes complete with the Type K bead wire temperature probe and one 9V battery.
