HS Digital Humidity Sensor
Serial Number:
This digital sensor has been computer profiled and calibrated at multiple relative humidity levels using standards traceable to
the National Institute of Standards and Technology through test #H-4622.
The humidity standard produces an atmosphere of known humidity based on the "two-pressure" principal which is to saturate
an air stream with water vapor at a given pressure and temperature. The saturated air stream is then reduced to test pressure.
The humidity at test pressure is then the ratio of the two absolute pressures, corrected for vapor pressure and enhancement
factor ratios.
