The Vaisala HUMICAP® Humidity
and Temperature Transmitter Series
HMT360 are the ideal solution for
measuring humidity in hazardous areas.
They operate safely and reliably even
in the most hazardous classifications.
The HMT360 transmitters' proven
performance and technology conform
with rigorous international standards.
HMP361 - wall mount
HMP363 - confined spaces
HMP364 - pressurized spaces
HMP365 - high temperature
HMP367 - high humidity
HMP368 - pressurized
pipelines

The entire HMT360 transmitter can be
installed directly in explosive areas. It
can withstand continuous exposure to
potentially explosive environments that
contain flammable gases or dust.
Due to the microprocessor based
electronics, options and accessories,
the HMT360 series is truly flexible.
Customers may specify the transmitter
configuration when ordering the
instrument, however changes in
configuration can also easily be made
in the field.
The interchangeable probes enable fast
and easy removal or re-installation
when required. Calibration, for
example, is easy to perform due to
the modular structure. All calibration
coefficients are included in the probe
unit itself, which means that probes
can be switched between transmitter
bodies without losing the accuracy.

|
In addition to the standard Vaisala
HUMICAP® Sensor, an application
specific, very chemically durable
sensor is also available.
The HMT360 transmitters are an
investment; their rugged design,
combined with trouble-free operation,
ensure a long-term solution for
monitoring humidity and dewpoint in
explosive environments.
Customized calibration and
maintenance contracts for the
HMT360 series are available on request.
