SEM161/162 RH & Temperature Transmitter

Brand: Status Instruments

The SEM161 /162 series are a cost effective “smart” humidity and temperature transmitter with a single two wire (4-20) mA output (SEM161) or dual two wire (4-20) mA output (SEM162). 

The design uses a digital sensor which plugs into the sensor stem. A 4 digit display option is also available. 

The product will measure humidity, temperature, dew point and delta T (the difference between dewpoint and ambient temperature) values. 

Using our free software, available on our website, PC configuration allows you to measure any one of these 4 parameters on the SEM161, or any two on the SEM162.
