Vaisala HUMICAP® Humidity and Temperature
Transmitters HMT120 and HMT130
Features/Benefits
The HMT120/130 with and without a display.
The Vaisala HUMICAP® Humidity and
Temperature Transmittersw HMT120
and HMT130 are designed for
humidity and temperature monitoring
in cleanrooms and are also suitable
for demanding HVAC applications.
Performance
The HMT120/130 incorporates Vaisala
HUMICAP® technology that measures
relative humidity accurately and
reliably. The Vaisala HUMICAP® is
resistant to dust and most chemicals.
The transmitter enclosure is
optimized for use in cleanrooms.
The smooth surface of the enclosure
makes it easy to clean and the
enclosure material is chosen
to tolerate purifying agents.
Furthermore, the cabling can be
done through the back wall of the
transmitter.
Interchangeable Probe
The HMT120/130 transmitters use
a fully interchangeable relative
humity probe. The probe can be
easily removed and replaced with
a new one without having to adjust
the transmitter, which allows for
easy and quick recalibration of
the transmitter. The probe can
be adjusted using one of Vaisala’s
portable meters as a reference.
Also available is a constant output
probe with fixed RH and T output
for convenient inspection of the
monitoring system and signal
transfer line.

Available Options
The HMT120 and HMT130
transmitters are available as wall
mounted or with remote probe. For
high temperature applications or
where space is limited, the remote
probe is ideal. The transmitters
come with an optional, LCD display,
which shows the measurement
results of selected parameters in
selected units. The parameters
are displayed simultaeously at two
separate rows on the display.
