The 922 Differential Thermometer.
Dual channel thermometer 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
thermometer; 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.
