Temperature measuring
instrument (2-channel)

testo 922 – For fast (differential)
temperature measurement

Ideally suited for applications in the HVAC field

2-channel temperature measuring instrument with optional

wireless probes

Display of differential temperature

TopSafe, the indestructible protective cover, protects from

dirt and impact

Continuous display of min./max. values

Hold-button for freezing measurement values

Cyclic printing of measurement values, e.g. once per minute

testo 922 is a temperature measuring instrument which

is especially suited to applications in the HVAC field. The

measuring instrument records the temperature values of

two connected thermocouple probes, and shows these

simultaneously together with the differential temperature in

the display. Measurement data transfer by radio additionally

allows the measurement value from a further temperature

probe to be displayed wirelessly.

With the TopSafe, and the probe plugged in, the measuring

instrument has protection class IP65.

°C

The instrument continuously displays the minimum and

maximum values. The measurement values shown in the

display (current measurement value, fixed measurement

value or the minimum/maximum value) can be printed out

on site using the Testo report printer (optional). In addiition

to this, the measurement values can be cyclically printed –

the intervals can be individually set.
