922 Differential Thermometer.
testo 922, 2 channel temperature measuring instrument T/C Type K, connection of an optional radio probe, with battery and calibration protocol.
The differential thermometer records temperature values from 2 connected thermocouple probes and displays them simultaneously. The reading from an additional temperature probe can also be wirelessly displayed in the testo 922 measuring instrument; i.e. measurement data is transmitted by radio. Differential temperature can be called up immediately. Current measurement data such as max/min data can be printed on the Testo printer on site. It is possible to print measurement data once a minute, for example, on the printer if cyclical printing is in operation.
