The humidity test chamber is highly stable and allows the evaluation of relative humidity sensors in the range of 5 to 95 per cent rh. Up to seven probes with different diameters and output signals can be validated simultaneously. The HygroCal100’s innovative design allows the probes to be integrated with the chamber and user interface enabling the operator to easily monitor the readings of each probe during the calibration cycle.
An external reference hygrometer, such as Michell’s chilled mirror Optidew Vision, can be integrated into the system. If this reference has a traceable calibration, it allows users to incorporate this traceability into their verifications.
