The ADG400 is designed for use as part of a hygrometry calibration system. It is capable of repeatable generation of dew points across a range of -80 °C...+20 °C, when used in conjunction with the Michell Instruments PSD2 pressure swing dryer.
The generation technique is based on the volumetric mixing of dry and wet gases. It gives the fastest response when changing between set points in comparison to other dew-point generator technologies (such as two-temperature, two-pressure or a combination of both).
The HMI allows the dew point to be changed and automated calibration profiles to be designed and run. The USB interface allows remote control of the HMI and integration with customer software.
