HM70 Hand-Held Humidity and Temperature
Meter for Spot-Checking Applications
The Vaisala HUMICAP
®
Hand-Held
Humidity and Temperature Meter
HM70 is designed for demanding
humidity measurements in spot-
checking applications. It is also ideal
for  eld checking and calibration of
Vaisala's  xed humidity instruments.
The HM70 incorporates the latest
generation of the Vaisala HUMICAP
®
Sensor. It is reliable and has better
than ever long-term stability.
Additionally, it has a sensor that
copes well with chemical interference
and provides accuracy that lasts in
demanding conditions.
The chemical purge option
maintains measurement accuracy
in environments with high
concentrations of chemicals. The
sensor preheat option reduces
measurement delays as it keeps
the sensor dry when the probe
is inserted into hot and humid
processes.
The Vaisala HUMICAP
®
Hand-Held Humidity and Temperature Meter HM70 is a high-
performance, portable humidity reference that is exciting to use.
Three probes
to choose from
The HMP75 is a general purpose
probe whereas the HMP76 is a long,
stainless steel probe especially
suitable for spot-checking in ducts.
The HMP77 is a small probe at the
end of a 5-meter cable. The probe is
ideal for dif cult-to-reach areas and
for on-site calibration of Vaisala's
process transmitters.
In addition, the HM70 supports the
use of Vaisala's dewpoint, carbon
dioxide and moisture in oil probes,
allowing measurements in several
multiparameter applications.
MI70 Link
The optional MI70 Link Windows
®
software and the USB connection
cable form a practical tool for
transferring logged data and real
time measurement data from the
HM70 to a PC.
