Vaisala HMP110 Specifications
Vaisala HUMICAP® Humidity and Temperature
Probe HMP110
The HMP110 with excellent stability and high chemical tolerance.
Several outputs
Miniature-size humidity
Low power consumption
and fast startup for battery
powered applications
The temperature measurement
is a standard feature, dew point
measurement is optional. Three
standard voltage outputs are
Measurement range:
0 ... 100 %RH; -40 ... +80°C
Cable detachable with
standard M8 quick connector
Reliable: Latest generation
HUMICAP® 180R sensor for
best stability and high chemical
tolerance. IP65 metal housing.
The HMP110 is a trouble-free and
cost-effective humidity transmitter
with high accuracy and good
stability. It is suitable for volume
applications or integration into other
manufacturers’ equipment. The
HMP110 is also suitable for glove
boxes, greenhouses, fermentation
and stability chambers, data loggers,
and incubators.
Optional RS485 digital output
Traceable: Comes with
calibration certificate. ±1.7%RH
measurement accuracy
(0 ... 90%RH)
HMP110R replacement probe
service available for easy
Optional dew point calculation
Easy installation
The probe cable has a screw-on
quick connector for easy installation.
Different cable lengths and
accessories are available.
Low current consumption
HMP110 is suitable for batterypowered applications because of its
very low current consumption. It also
has a fast start-up time.
Robust design
The aluminum body of the HMP110
is classified as IP65. Thus, it survives
rough conditions. The HMP110 has
high chemical tolerance because of
the HUMICAP® 180R sensor.
Easy maintenance
Maintaining measurement
traceability is easy using the
HMP110R replacement probe. We
send you a replacement probe, you
detach the old probe and send it back
to us. In this way the measurement
is available at all times without
