Meteorological Installation Kit HMT330MIK

Note that the HMT330MIK is being discontinued. It is replaced by Indigo family products. Do not specify HMT300MIK for new projects, instead view Indigo transmitters and probes that are also designed for use in demanding applications.

Obtaining a true humidity reading is particularly important in e.g. fog and frost prediction and in traffic safety. The Vaisala Meteorological Installation Kit HMT330MIK enables the Vaisala HUMICAP® Humidity and Temperature Transmitter HMT337 to be installed outdoors to obtain reliable measurements for meteorological purposes. The installation kit can be ordered in a variety of configurations.


  • Patented, warmed probe prevents condensation
  • Ideal for measuring in water vapor injection applications
  • Warmed probe provides true humidity readings in condensing conditions
  • Humidity measurement expressed as relative humidity and/or dew point temperature
  • Easy field calibration with the HM70 hand-held meter
