The testo 925 is a 1-channel temperature measuring
instrument which is particularly suitable for applications in
the HVAC field.
The instrument is optimum for the connection of fast and reliable thermocouple probes.
Using measurement data transfer by radio, the measurement value
of a further temperature probe can be additionally displayed
The protective cover TopSafe ensures water- and
dirt-proofness when a probe is connected.

The instrument reliably and continuously displays the minimum and
maximum measurement values.

The measurement values shown in the display (current measurement value, frozen measurement value, or the minimum/maximum values) can be printed out via the Testo report printer (optional).
The user can store limit values in the instrument himself; as
soon as these upper and lower values are violated, an audible signal sounds.
