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 temperatureprobe, 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.
