HFRR Humidity and Temperature probe including cable & bracket (HFRHYG)
Description
An optional combined humidity and temperature probe can be connected to the rear of the HFRR control unit. For some test procedures the wear scar must be adjusted to compensate for the effect of fuel moisture content on the result. The probe will automatically measure the ambient temperature and humidity at the start and end of the test, instead of the user having to make the measurements manually.
Supplied components
- HFRR Humidity and Temperature probe
- Probe connecting cable
- Probe bracket (not required if using an HFRR Humidity Controlled Cabinet )
The connecting cable attaches to the rear of the control unit as shown below:

The bracket supplied is fitted to the right hand side of the instrument (when viewed from the test chamber end) using the front cover screw as shown above.
The HFRR humidity and temperature probe can be purchased separately without cable and bracket. The part code for this item is HFRHUM.
