DESCRIPTION

Vaisala’s Models HMD60 and HMD70 Duct Mount Relative

Humidity Transmitters have been speciﬁcally designed

for use in HVAC/BAS and pharmaceutical applications.

These instruments measure relative humidity from 0% to

100%. They are easily installed and meet the European CE

standards.

Five-minute ﬁeld calibration is possible using the Model

HMK41K Humidity Calibrator. When accuracy adjustment

or sensor replacement is necessary, the transmitter can be

calibrated in seconds with a single potentiometer without

disturbing operation. This saves hours of maintenance time

and assures high accuracy.

FEATURES

• Comes with NIST certiﬁcate

• Full 0% to 100% RH measurement

• State-of-the-art replaceable sensor technology
