Thermometer temperature range covers –328 to 2498°F and –200 to 1370°C. Resolution is 0.1 from –200 to 640°C (–328 to 990°F) otherwise 1°. Meter only accuracy is ±1°C. Supplied stainless-steel, triple-purpose, Type-K thermocouple probe may be used to measure temperatures of liquids, air/gas, and semisolids. Large, 1/2-inch-high LCD is easy to read. Thermometer accepts any Type-K probe. Minimum and maximum readings may be recalled instantly. Unit features backlit display so that answers may be read in poor lighting— even total darkness. Count-up timer provides a relative time measurement while taking temperatures and recording MIN/MAX. Traceable Products have an individually-numbered Traceable Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA.
