The humidity generators of the HGC series enable the automatic control of relative humidity in the range of 5 % to 90 % in small and medium-sized closed measuring chambers. The humidity generators can be connected to the measuring chambers of many DataPhysics Instruments systems. They can also be combined with laboratory measuring instruments of other manufacturers.

The HGC 20 humidity generator can independently generate a dry air flow from the ambient air, using its integrated pump and the desiccant reservoir. Together with the heated water container, the desired humidity can then be produced. The flow rate is constant at 600 millilitres per minute.

The HGC 30 can generate humidity not only by utilising ambient air and the built-in heatable water container, but also via an external gas supply with compressed air, nitrogen, and argon. Variable flow rates between 70 and 600 ml/min with ambient air and 70 to 3500 ml/min are possible. The integrated pressure regulator is specially calibrated for nitrogen and argon. 

Features of the humidity generators:

• control and generation of relative humidity in the range of 5% to 90%

• independent generation of dry air from ambient air

• heatable water container

• heated gas connection tube to the measuring chamber avoids condensation

• calculation of the dew point in the measuring chamber

• automatic drying of the desiccant by built-in heating in two alternately used desiccant flasks

• easy control via built-in touch screen or optional software

• serial RS 485 or USB interface
