  Description

  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.

  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.
