The GH1 and GH2 humidity generators are designed to verify and calibrate humidity probes with their electronics. They can be used to generate water contents as low as 1 part per million in volume, equivalent to a -76°C dew point temperature, up to saturation at ambient temperatures.
Gruter & Marchand offers the entire turnkey system, including the generation of ultra-dry air, the generator (GH1 or GH2), and the certified EDGETECH chilled mirror reference hygrometer, along with technical assistance for installation and use.
