HMW95 BACnet/Modbus Humidity, Dew point and Temperature Sensor for High Performance HVAC, Wall Model, 1.7% accuracy

The digital HMW95 transmitter is designed for use in high performance HVAC applications such as museums, laboratories, data centers, and production facilities. The transmitter is quick and easy to install and use on the field even without any special tools.
 
The HMW95 transmitter features both BACnet MS/TP and Modbus RTU output options. The transmitter can be set up using simple tools.

On-site calibration and adjustment is exceptionally easy. The sliding cover 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 any changes. A service port enables 2-point calibration, using either a PC or the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70.

Both models feature a display for easy calibration, but in model HMW95 the display is hidden behind a solid front enclosure.

The transmitter has a user exchangeable humidity and temperature module, which can be ordered as a spare part. The module is delivered with a calibration certificate.

The package includes:

  • HMW95 transmitter with a display and a sliding cover with either a display opening or a solid front
  • Calibration certificate (ISO9001 compliant, traceable)
  • User's Guide, multiple languages
