Particle & Surface Sciences introduces the new HGC 20 humidity generator and controller developed by Dataphysics.
HGC 20 humidity generator and controller can be combined with all optical contact angle measuring instruments of the OCA series to allow measurement of static and dynamic contact angles as well as surface tension depending on the relative humidity.
The new series of humidity generators and controllers is available in two variants: HGC 20 and HGC 20EC. Dried air in both models is generated via a special desiccant, allowing their use independently from any dry-gas source. The HGC 20 also allows the automatic regeneration of the drying agent, which enables long term measurements without any problems. Depending on the dew point, relative humidity between 5% and 90% can be generated.
Older instruments can be upgraded easily in combination with the optical contact angle measurement devices of the OCA series as well as the environmental chambers TFC 100 or TPC 150.
