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. 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.
Therma Elite
The Therma Elite incorporates all the features of a Therma 1 thermometer (221-041) , but with the addition of a backlit display, max/min memory function and a mode button for the selection of 0.1/1 °C/°F. The thermometer also incorporates a calibration trim function (±2 °C) which allows users to compensate for thermocouple probe errors.
Optional Accessories
The 830-251 protective silicone boot – the Therma series is waterproof to IP63 when used in conjunction with this protective boot. The 832-050 wall-mounted thermometer holder stores the thermometer safely when not in use (screws not supplied).
