Vaisala Humicap hand-held humidity and temperature meter HM40 is available as both a standard and remote probe. The remote probe alternative further increases the versatility of the hand-held meter by enabling convenient measurements in ducts and other difficult-to-reach or confined places.
Other features, including an interchangeble Vaisala HMP113 measurement probe, make the Vaisala HM40 a suitable spot-checking tool for portable humidity measurement needs including HVAC applications.
The compact HM40 is said to provide reliable measurement 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, proving the sensor’s excellence in terms of long-term stability and the ability to cope with chemical interference.
