HGC – Humidity Generator and Controller | Dataphysics

Humidity Generator and Controller – HGC Series
The humidity generators of the HGC series enable reliable control of relative humidity in the range from 5% to 90% in small environmental measurement chambers, either from DataPhysics Instruments or from other manufacturers. With an integrated pump and a desiccant reservoir, these generators can independently produce a flow of dry air using ambient air. Using a heated water reservoir, the required humidity can be generated directly inside the HGC device.

Using a gas connection tube, this flow of air with well-defined humidity can be directed to various environmental chambers or laboratory devices. The transfer tube is heated to prevent condensation during the transport of humidified air. With the help of an additional humidity and temperature sensor, the system can measure directly at the target location and can calculate the dew point inside the environmental chamber.

Thanks to the integrated touchscreen, the system can be used without additional software, being immediately ready for operation. Of course, the integrated software of the DataPhysics Instruments measurement instruments includes HGC humidity control.
