HM34 Pocket Size Relative Humidity Meter
The Vaisala HUMICAP® Hand-Held
Humidity and Temperature Meter
HM34 provides a fast and convenient
way to accurately spot-check relative
humidity and temperature.
Fast and easy-to-use
In measurement mode, the
extendable probe just slides out.
Normally, measurement takes only
a few seconds. The HM34 meter
includes a HOLD button which
allows the user to retain an RH or T
measurement until it has been noted
or recorded.
The Vaisala HUMICAP® Hand-Held
Humidity and Temperature Meter
HM34 provides accurate spot checks of
humidity and temperature.
If no buttons are pressed for three
minutes, the unit automatically
switches itself off. This automatic
POWER-OFF function prevents the
possibility of accidental discharge of
the HM34’s battery.
After the measurement is completed,
the probe is slid back into the meter
casing. Between spot checks, the
meter is normally stored in its
carrying case.
