Product Options


The DewPro MMY30 is a dew point transmitter for analyzing moisture content in dessicant air dryers, pipeline natural gas and industrial gases. It is a loop powered transmitter with 4 to 20 mA output. The MMY30 has been specifically deigned to measure dew point or ppm in gases at line pressure or atmospheric pressure. It features an integral flow cell for filtration and flow regulation making it ideal for monitoring the moisture content in various process environments. There are also several options available for the process connection allowing easy installation of the transmitter.
