The Therma 1, 3 and Elite digital thermometers are rugged and easy to use instruments that operate through the range of -100 to 1370 �C with a 0.1 �C or 1 �C resolution (dependent on model - see specification table below). The thermometers are housed in a robust ABS case that contains 'Biomaster' additive that helps to reduce bacterial growth.  
The Therma 1 and 3 feature a large, easy to read, LCD display 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 units will power off automatically after ten minutes, maximising battery life. This feature can be disabled by the user, if required. 
ETI offers an extensive range of interchangeable thermocouple type K probes for a variety of different applications. The Therma 1 is priced excluding probe.
