HGC – Humidity generator and controller

With the humidity generators and controllers of the HGC series the relative humidity can be controlled inside of small measuring chambers. Hence, the influence of humidity on interfacial parameters can be investigated in combination with another measuring device from DataPhysics Instruments. The HGC series work as stand-alone devices and are also available as OEM products.

Humidity as an interfacial parameter

Moss or mould on a facade is an unsightly problem that occurs as a result of high and long-lasting surface humidity. In order to investigate which surface properties lead to or promote the fastest drying under high humidity, the conditions that prevail during the formation of morning dew can be simulated with a humidity generator of the HGC series.

Due to the wide relative humidity range the HGC series can reproduce humidity conditions from very humid like in the tropical rainforest to extremely arid like in the desert.

The HGC models

The humidity generators of the HGC series allow for a reliable control of the relative humidity, in the range of 5% to 90%, inside small environmental measuring chambers from DataPhysics Instruments or other suppliers. Due to the integrated touch screen the system can be operated without additional software and is directly ready for use. Of course, the software of the DataPhysics Instruments measuring instruments includes, integrated, HGC humidity control.
