Vaisala HMW82 Humidity and Temperature Transmitter for Wall Mounting in Commercial HVAC Use, Loop-Powered

The 2-wire HMW82 transmitter is designed for use in energy management systems in buildings. These temperature humidity meters combine excellent stability with reliable operation. It is easy to install: wire it to the terminal block at the transmitter bottom and close the housing with a snap-on lid to cover the electronics. The Vaisala HMW82 temperature humidity meters are designed to fit standard 2x4" junction boxes.

The Vaisala HMW82 uses the interchangeable Vaisala INTERCAP® sensor which requires no recalibration when the sensor is replaced. The sensor is also insensitive to dust as well as to most chemicals.

The Vaisala HMW82 temperature humidity meters have two 4-20 mA loop-powered outputs corresponding to 0…100% RH and -5…+55 °C (+23…+131 °F) temperature.
