HMT100 Series Humidity and Temperature
Transmitter for Demanding HVAC Applications
The Vaisala HUMICAP
®
Humidity
and Temperature Transmitter Series
HMT100 are designed for humidity
and temperature monitoring in
demanding environments.
Typical applications include stability
rooms, HVAC, livestock farms,
greenhouses, indoor swimming
pools, and outdoor applications.
Performance
HMT100 incorporates Vaisala
HUMICAP
®
technology that measures
relative humidity accurately and
reliably. Vaisala HUMICAP
®
is also
resistant to dust and most chemicals.
Available options
The HMT100 is available as a wall
mount or remote probe model with
an optional display. For high
temperature applications or where
space is limited, the remote probe is
ideal.
HMT100 remote probe and wall mount models.
HMT100 can show relative humidity
only, dewpoint only, or relative
humidity and temperature, or
dewpoint and temperature readings.
The probes are interchangeable
without having to calibrate or adjust
the transmitter.
HMT100 can also be installed
outdoors using an installation kit,
or directly into an air conditioning
channel using a duct installation kit.
Annual calibration
Calibration is recommended typically
at an interval of one year using either
the Vaisala HUMICAP
®
Hand-held
Humidity and Temperature Meter
HM70 or the Vaisala HUMICAP
®
Humidity Indicator HMI41.
The accuracy of the instrument can
also be checked using the Vaisala
Humidity Calibrator HMK15, which is
based on saturated salt solutions.
