The Edgetech RH CAL portable relative humidity calibrator features optical chilled mirror technology and is entirely self-sufficient. It does not need compressed air or a water connection to operate, which allows this Edgetech system to be truly portable. The Edgetech RH CAL is a microprocessor-based, programmable humidity calibration system that can perform on-site, NIST traceable calibrations.

The Edgetech RH CAL system offers the highest accuracy available for both relative humidity (±0.5%) and ambient temperature (±0.1°C). With RH CAL, temperature and relative humidity are controlled independently; therefore you are not limited to performing calibrations at the surrounding ambient temperature.

Other features of the Edgetech RH CAL portable relative humidity calibrator include automatic balance cycle (ABC), and an integral ambient temperature probe and D2 chilled mirror sensor which are located in the sample chamber providing not only superior accuracy, but the fastest response as well.
