Key Benefits
The RH CAL is a programmable humidity calibration system that is at home in the metrology lab or in the field, performing on-site, NIST traceable humidity calibrations. The system provides very high accuracy for both relative humidity and temperature. Unlike other calibration systems, the RH CAL does not need compressed air or a water connection to operate, which allows the system to be truly portable. With the RH CAL, temperature and relative humidity are controlled independently. The user is not limited to performing calibrations at the surrounding ambient temperature, which may not be appropriate for his unique calibration protocol. Using Edgetech Instruments’ chilled mirror, primary method dew/frost point measurement technique for traceability and feedback control, RH CAL is a laboratory grade, standalone, portable humidity calibration system.
