AMT

Dewpoint Hygrometer

The new model AMT-20 is probably the smallest 4-20 mA – 3-wire transmitter on the market today. It is a fully digital dew point transmitter, which is protected against all environmental influences by a complete stainless steel housing and is ideally suited for industrial applications. Besides the 4-20 mA current loop the AMT-20-Ex also offers a digital output.
