The Vaisala HMW90 Series Humidity and Temperature Transmitters measure relative humidity and temperature in indoor environments, where high accuracy, stability, and reliable operation are required.

The HMW90 series includes models for both current and voltage output. These flexible transmitters offer a variety of options and features. Transmitters include a display and a sliding cover with either a display opening or a solid front. Output options include both special scalings and calculated dew point and mixing ratio parameters.

The HMW90 series transmitters are quick and easy to install. The wiring is connected through the back plate and the electronics with the sensors can then be easily snapped on after wiring is completed.

Dip switches for transmitter configuration can be accessed when the enclosure is open. The most common settings, such as metric/ non-metric unit selection and relay set-point, can be easily changed without special tools.

On-site calibration and adjustment is exceptionally easy. The sliding lid exposes offset trimmers for 1-point calibration of both humidity and temperature parameters. The included display makes adjustment clear and convenient by instantly indicating the effects of changes. A service port enables 2-point calibration, using either a PC or the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70. The HMW90 series transmitters include a user exchangeable Humidity and Temperature Module HTM10, which can be ordered as a spare part. The module is delivered with a calibration certificate. Calibration and repair services are available through all Vaisala Service Centers.

Typical applications for the Vaisala HMW90 Series Humidity and Temperature Transmitters are:

  • Museums and archive facilities
  • Production and warehouse facilities
  • Data centers
  • Laboratories
  • Testing environments
