HMT120 Clean Room and HVAC Dewpoint and Temperature Transmitter, Wall Model, Display, Current Loop

The HMT120 is designed for dew point and temperature monitoring in cleanrooms and it is also well suited for demanding HVAC applications. The smooth surface of the enclosure tolerates cleaning agents well and the surface is easy to clean. The HMT120 transmitters use a fully interchangeable sensor probe. It can be easily removed and replaced without having to adjust the transmitter, which allows for easy and quick recalibration of the transmitter.

This transmitter model features a 2-line LCD display on the front cover. Please choose whether you'd like to see metric or non-metric units displayed.

The HMT120 has two 4…20 mA loop-powered outputs corresponding to -20…+80 °C (-4…+176°F) dew point and -40…+60 °C (-40…+140 ° F) temperature.
