Humidity calibrator Fensor HG-101

In the laboratory or in the field, the HG-101 humidity calibrator is more than ever the ideal tool for calibrating recorders or probes for measuring relative humidity.

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. Free apps for Android and Windows.

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.

Humidity calibration can be performed over a temperature range of +5 to +50 °C by placing the HG101 in a climatic chamber. Set points can be changed remotely through the HG101s USB interface and control software installed on a PC, tablet or smartphone.

The HG-101 is designed to be used within a thermostatically controlled chamber or enclosure, without compromising the homogeneity of the temperature inside the HG101 measuring chamber. To do this, the materials used for the calibrator were selected to promote thermal diffusivity and low hygroscopicity.

To reduce uncertainty and external influences, the structure is configured to minimize cold spots, promote heat distribution and ensure consistency in temperature. As relative humidity is so temperature dependent, this means the temperature related contributions to RH calibration uncertainty are minimised.
