Handheld meters

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.
