Description

The Omega RHCL-2 is a microprocessor based, programmable humidity calibration system that is at home in the metrology lab or out in the field performing on site NIST traceable humidity calibrations. The RHCL-2 is entirely self-sufficient and does not need compressed air or a water connection to operate, which allows this system to be truly portable. The system offers the highest accuracy available for both relative humidity and ambient temperature.
Temperature and relative humidity are controlled independently; therefore, you are not limited to performing calibrations at the surrounding ambient temperature.
The RHCL-2 uses an Optical Chilled Mirror (OCM) primary measurement technique for traceability and feedback control. Contributing to ease of use are features such as maintenance reducing Automatic Balance Cycle (ABC), 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.
The RHCL-2 employs a unique control scheme for maintaining precise RH control. The system incorporates volumetric proportional control valves. By independently modulating the "Dry" and "Wet" valves from full-open to full-close, and all points between, any desired humidity can be quickly generated. Additionally, because the RHCL-2 is continuously monitoring the sample chamber conditions via its integral chilled mirror, it is able to instantaneously react to changes in humidity and maintain control stability.
