HMM210 Series Humidity Modules
for Environmental Chambers
The Vaisala HUMICAP
®
Humidity
and Temperature Module Series
HMM210 are designed for OEM type
applications needing humidity or
dewpoint measurement in demanding
environments, e.g. in environmental
chambers growth chambers and
incubators.
Demanding applications
The HMM210 modules are optimized
for harsh environments with
both high humidities and a wide
temperature range. The humidity
measurement is fully temperature
compensated. In addition, the
modules remain accurate and reliable
under extreme conditions where a
combination of high humidity and
rapidly changing temperature can
result in condensation on the sensor
head.
The modules are highly versatile
and exible. They provide either

modules are especially suitable for demanding OEM applications,
e.g. environmental chambers and incubators.
relative humidity and temperature or
dewpoint measurement with various
congurations. All modules have
microprocessor based electronics
and are equipped with analog or
digital outputs.
Unique warmed probe
The warmed probe and composite
sensor, available on the dewpoint
probe conguration, is warmed to
always remain a few degrees higher
than ambient. Advantages of this
patented technique include:

high humidities.
Vaisala HUMICAP® Sensor
and chemical purge
option
The HMM210 modules use
Vaisala HUMICAP
®
180R sensors
for best possible stability. The
sensor is insensitive to dust and
to most chemicals. In conditions
of extraordinary high levels of
chemicals and cleaning agents,
chemical purge is available as
an option. With chemical purge,
contaminants are evaporated from
the sensor and performance is
returned to normal.
Features/Benefits
▪
Three probe configurations:
▪
Relative humidity (RH) plus
temperature (T) probe.
▪
Dewpoint probe with probe
heating. By heating the whole
probe a few degrees above
ambient condensation is
avoided.
▪
Dewpoint probe described
above, together with a
temperature probe for
obtaining relative humidity and
temperature outputs.
▪
Three module configurations
▪
Dierent probe and cable
lengths
▪
Chemical purge option
maintains high measurement
performance in demanding
chemicalconditions.
▪
Calibration certificate included
