HMI41 Indicator and
HMP46 High Temperature Probe
The Vaisala HUMICAP
®
Humidity
Indicator HMI41 tted with the
Vaisala HUMICAP
®
Humidity and
Temperature Probe HMP46 can be
used for spot checking humidity
and temperature in ducts or
chambers. Typical applications
are plant maintenance, installation
and inspection of air conditioning
systems, production and storage
areas and production processes.
In addition, it is suitable for eld
checking Vaisala's humidity
transmitters.
Withstands high
temperatures
The HMP46 operates in full
humidity range of 0 ... 100 %RH. The
temperature range is from
-40 to +100 °C (-40 ... +212 °F). For
short periods of time, the probe can
withstand temperatures up to
+180 °C (+356 °F).
The HMP46 probe is solid and
rugged. Its stainless steel probe is
made to withstand rough handling
in mechanically demanding
applications. The probe’s long
shaft can also reach otherwise
unreachable places.
Versatile and easy to use
In addition to displaying the humidity
and temperature readings, the HMI41
indicator calculates dewpoint and
wet bulb temperature, absolute
humidity and mixing ratio.
The indicator has an easy-to-read
two line liquid crystal display. The
display units (metric or non-metric)
are easily selected.
The Vaisala HUMICAP
®
Humidity
Indicator HMI41 equipped with the
Vaisala HUMICAP
®
Humidity and
Temperature Probe HMP46 is an ideal
combination for spot checking and field
calibration.
These features, plus fast response
time, high measurement accuracy
and excellent stability, as well as
the wide temperature range of the
probe, make the HMI41/HMP46
combination an ideal choice for the
most demanding applications.
High performance sensor
The HMP46 probe incorporates
Vaisala HUMICAP
®
Sensor. This
sensor has high accuracy, excellent
long-term stability and negligible
hysteresis. In addition, the sensor is
insensitive to dust, particulate dirt
and most chemicals.
