The HygroGen HG2 humidity generator can be used for the calibration of up to five relative humidity probes simultaneously. The HG2 humidity generator typically requires less than 5 minutes to equilibrate from one humidity condition to another when temperature is kept constant. This is accomplished by using a mixed flow method to precisely generate a known humidity and temperature condition within a well insulated chamber. A desiccant cartridge provides low humidity and a saturator provides high humidity. These are mixed together by a control system to create stable humidity within the range of 5 to 95 %RH. Temperature is controlled with a thermoelectric heat pump and can be set within the range of 0 to 60 °C.
The HG2 humidity generator is a self-contained unit that requires no external resources except mains power. It can also be used together with an external chilled mirror reference instrument. The HG2 features a user friendly touch screen graphical interface as well as a programmable ramp and soak function with multiple steps and profiles. The HG2 humidity generator is pre-loaded with the ROTRONIC HW4-P data acquisition software which is used for calibrating and adjusting the ROTRONIC humidity temperature probes and instruments.
