TERMIO-31 is equipped with MiniTherma socket. It allows the User to change the K type thermocouple probes easily.

Accuracy of each data logger is set individually in calibration process and it depends on measuring range. For example, the accuracy in range from 0°C to 200 °C is better than 0,6°C.

Termio-31 thermocouple data loggers weigh only 85 grams, including battery and features a easy to read LCD display with low battery indication, 3/1 digit LDC with 0,1°C resolution in range from -200°C to 1000°C. In range from 1000°C to 1400°C the resolution equals 1°C.

Termio-31 display provides information including current measurement reading, threshold exceeded, min/max values, remaining battery power.

Each data logger incorporates a red LED indicates when customized thresholds have been exceeded.

Termio-31 is housed in ergonomic ABS plastic case, resistant to dust, dirt and water (IP 65).

Termio-31 can be connected to a computer via a USB logger cradle

The USB logger cradle works with a free LogSoft app, which can be installed on Windows. LogSoft is a programme that can be used with Win 10, Win 7 and Win 8. Application is available on Termoprodukt website.

The software allows to programme the logging sample/interval rate from 0.1 sec.,the real-time clock , user can programme delayed start from clock/calendar or start from button, after filing memory overwriting or stop.

Termio-31 creates a new files which contains registered data. Data can be easily displayed as graph and table, printed or saved in .txt or .pdf format.

Transmission time of 32000 saved measurements from the device to a computer equals max. 60 seconds. It is a very comfortable solution, especially in case of possessing more than 1 device.

When ordering loggers it is necessary to order at least one USB logger cradle.

Wall bracket to fasten the device to a wall to buy extra. The handle can protect the device from mechanical damage or undesirable action of other people.
