DataPhysics – 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.

Humidity is an important parameter for many different material analysis systems. Since the humidity generators and controllers of the HGC series can work stand-alone and are available as OEM products, they can be used for many laboratory applications and devices. For example Verpaalen et al. were able to investigate a bioinspired bilayer actuator that changes its bending angle depending on temperature and humidity using a HGC 30.
