Ov erview of the Humilab
T he Humilab Relative Humidity Generator is designed to perform
U.S. National Institute of Standards and Technology (N.I.S.T.) trace-
able calibration of RH instruments and/or several smaller transmit-
ters.
The Humilab design is based on the proven divided flow tech-
nology. Divided flow in the time domain excels as a reliable
method for accurately controlling relative humidity at a fixed
temperature. Temperature stability is ensured by a water jacket
surrounding the calibration chamber.
Continuous digital control, using a built-in GE General Eastern
N.I.S.T. traceable chilled mirror dew point hygrometer, makes the
Humilab a traceable relative humidity transfer standard with which
to calibrate other devices. Calibrations meeting the requirements of
ANSI Z540-l-1994, MIL-STD 45662A, 10CFR-50, and ISO 9001 may
be performed.
The included Prostep software allows you to use your PC to upload
a control profile via the RS-232 port, enabling an entire calibration
cycle to be run.
