The HM40 is a compact and portable humidity meter at hand everywhere you go. It is an ideal spot checking tool that is easy to use and provides reliable measurement. It can be used for a wide range of various portable measurement applications. According to a user's needs, the meter is available in two models: standard and with a remote probe.

Simple and easy to use, the HM40 includes a user-friendly, large graphical display and easy-to-use push buttons. The user interface is simple and intuitive to use, and available in 10 languages. Also, many other settings can be modified by the user to best suit his individual needs. In addition to relative humidity and temperature, the HM40 provides five calculated humidity parameters, all available in both metric and nonmetric units.

The meter is powered by 2 AA-sized batteries. An external NiMH battery recharger with USB connection and rechargeable NiMH batteries are offered as an option. Each HM40 comes also with a handy belt clip and a case.

The calibration of the HM40 is easy: just send the meter back to a Vaisala Service Center for recalibration or simply plug in a recently calibrated interchangeable HMP113 measurement probe. Alternatively, the HM40 can be user calibrated on site using a humidity reference, e.g. the Vaisala Humidity Calibrator HMK15.
