Product Details

HM40 instrument is a portable device used for rapid measurement of humidity and temperature. Due to its ease of use, you can easily conduct various types of inspections or spot checks.

The Vaisala HM40 hygrometer is a portable humidity and temperature gauge. The instrument has a large, user-friendly graphical display screen and is easy to use through buttons. The interface is simple and intuitive, supporting 10 languages.

In addition to relative humidity and temperature, the instrument also provides 5 calculation parameters. HM40 can be calibrated using the Vaisala HMK15 calibration kit. It is powered by two AA batteries. A battery charger with USB connection is available as an option.

Currently, in 2016, Meters' products have been expanded to a new version:

HM41-HM40 with HMP113 probe, range up to+60 ° C, can be inserted into instruments
HM45-HMP113 probe insertion handle version, in addition to HM40HANDLE handle, with a range of up to+60 ° C
HM42- HMI41SET with probe HMP42- probe diameter 4mm 1000 ° C
HM46- HMI41SET with HMP46 probe - probe with operating temperature up to 180 ° C
HM40S - A set of probes+an instrument for structural measurement (such as concrete humidity)
SHM40- kits such as HM40S+suitcase and other inventory
