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.

Key features

  • Control and generation of relative humidity in the range of 5% to 90%
  • Stand alone generation of dry air without an external pressurized gas supply
  • Heated water reservoir
  • Heated connection gas tube (transfer line) to thermal chamber to avoid condensation
  • Flow rate: 70 … 600 ml/min with ambient air or 70 … 3500 ml/min with external gas supply
  • Easy control via touch-screen or software
  • Serial RS 485 or USB interface
  • Calculation of dew point in the measuring chamber
  • Automated drying and regeneration of desiccant by a built-in heating system in two alternatively used desiccant reservoirs (total stored desiccant amount about 1.0 kg)
  • Inlet for external gas supply of pressurised air, nitrogen or argon (only clean and oil free gases)
  • Integrated flow rate and pressure regulator calibrated for N2 and Ar
