The Therma 3  digital thermometer is a rugged and easy to use instrument that operates through the range of -100 to 1370 °C with a 0.1 °C or 1 °C resolution. The thermometers are housed in a robust zip-up case.

The Therma 3 features large, easy to read, LCD displays with open circuit ‘Err’ and low battery indication. Each thermometer is powered by three 1.5 volt AAA batteries that gives a minimum of five years battery life. The unit will power off automatically after ten minutes, maximising battery life. This feature can be disabled by the user, if required.

The Therma 3 is priced including probe.
