Working or Transfer Standard
In the calibration laboratory or workshop, the 473 provides the best possible measurement capability
for a working standard in controlled humidity conditions and humidity generators. By using the 473 for
continuous dew point and temperature reference measurement, users can achieve small uncertainties
and calibrate multiple probes in short time periods.
When an RH generator is used for on-site calibration, the combination of the RH generator, dew point
mirror and temperature measurement system may not be practical for site engineers as they need to
run calibrations quickly to minimize down-time. Examples of this situation include calibration of instru-
ments used in pharmaceutical production rooms, laboratories, and critical industrial processes. In this
case, the RH generator can be periodically validated using the 473 as a reference standard.
The user should define a working procedure to manage calibration traceability. Maintaining careful
calibration records and history for both the transfer standard and the generator is essential to properly
determine the calibration stability and drift components of uncertainty budgets. For further support,
