The Vaisala HUMICAP HMT310 series is for demanding industrial applications where compact product design is essential. The measurement stability is excellent. The instrument is easy to integrate, small in size, and insensitive to dust and most chemicals. The HMT310 series features several probe options for different application needs:

  • HMT311 for wall mounting
  • HMT313 for general use
  • HMT314 for high pressures up to 100 bar and vacuum conditions
  • HMT315 for high temperatures
  • HMT317 for high humidity and meteorological applications
  • HMT318 for pressurized pipelines up to 40 bar

Dimensions in mm [in]

Several Outputs, One Connector

HMT310 is powered up with 10 … 35 VDC. It has two analog outputs and an RS-232 serial output in one M12 8-pin connector. The output signal and the supply power travel in the same cable, the only cable connected to the unit.

Chemical Purge

Chemical purge helps to maintain measurement accuracy between calibration intervals. It involves heating the sensor to remove harmful chemicals.
The function can be initiated manually or programmed to occur at set intervals.

A Variety of Features to Choose From

The following optional features and accessories are available for the HMT310 series:

  • Warmed probe and sensor heating for high humidity conditions.
  • Chemical purge for applications risking interference with chemicals in the measuring environment.
  • Calculated humidity quantities.
  • Sensor protection options and probe cable lengths.
  • Mounting kits.
  • Rain shield.
