Compatible with both type K and type J thermocouples, the Extech TM300 allows users to carry out two measurements at the same time.

Depending on which thermocouple is equipped, the overall measurement range of this tester changes. With a type K probe equipped it features measurement range from -328 to 2501°F (-200 to 1372°C), whereas with a type J probe equipped it features range of -346 to 2012°F (-210 to 1100°C). All measurements are carried out with basic accuracy of ±(0.15% rdg + 1.8°F/1°C).

This thermometer is somewhat different in terms of design when compared with other Extech thermometers. The most notable difference is the lack of buttons on the front of the tester; Extech has instead moved these to the side of the device for easy one-handed operation when carrying out testing procedures. It also means that the front of the tester has a large, backlit LCD screen that clearly displays the temperature reading taken from the two equipped thermocouples. The screen can display T1, T2, T1-T2 differential and MIN, MAX and AVG.

The unit also contains a number of additional features including an auto power off function (which can be disabled) and a data hold function for temporarily storing test data.
