The Vaisala Humicap handheld
humidity and temperature meter,
HM40, is now available as both
standard and remote probe
models. The remote probe
alternative enables convenient
measurements in ducts and
other difficult-to-reach or
confined places.

Other features, including an
interchangeble Vaisala HMP113
measurement probe, make the
HM40 a suitable spot-checking
tool for a wide range of portable
humidity measurement needs.
Compact, simple and easy to use,
the device provides reliable results in
various environmental conditions. Its
humidity measurement is of the
same Vaisala Humicap sensor
technology that
recently landed on
Mars on board the
Curiosity Rover.

In addition to a wide
measurement range for
RH and temperature,
the HM40 provides
calculated quantities
for five other humidity
parameters.
