The Termio 31 digital thermometer is a reliable and simple device that measures temperatures between -200 and 1400 °C with a resolution of 0.1 or 1 °C. Therma Elite thermometers come with a lightweight ABS casing. 

The Termio 31 features easy to read, LCD display with open circuit 'Err' and low battery indication. Each thermometer is powered by 3.6 Volt 1/2 AA battery that gives approximately 2000 hours of battery life. 

Thermocouple data recorder Termio-31 is priced excluding probe. Termoprodukt offers interchangeable type K penetration and surface thermocouple probes. Termio-31 can be connected to any K-type probes equipped with mini plug.

The software allows to programme the record frequency from 1 second, the real-time clock , user can programme delayed start from clock/calendar or start from button, after filing up the memory it overwrites or stops. 

Registered data can be easily displayed as graphs, or saved in .pdf or .txt format.

Termio-31 creates many files with data - each time recording is started and stopped new file is created in memory.

Device can be calibrated on your own following instructions from calibrating user manual.

Calibration certificate for termio-31 data logger with ST-16  temperature probe, which was calibrated in two points 0°C and 100°C.

Verification certificate for termio-31.
