Once the instruments under test are inserted in to the test cell, the operator just needs to set the required humidity value using the panel mounted switches or by software through the USB interface.

The HG-101 is very fast to reach a target RH value in typically 30 seconds thanks to the innovative RDSa mixing system. Stability is better than ±0.2% over the range 10 to 90 %rh. Over the full 5 to 95 %rh range, extended stabilisation time is necessary to reach the best performance.

The HG-101 humidity generator does not use a liquid water reservoir, so it can be used in different positions depending on the requirements of the calibration. Similarly, no particular care (emptying, cleaning, drying) is required between uses or during transportation.
