Intrinsically Safe XDT Digital Dew Point Transmitter

The Intrinsically Safe XDT Digital Dew Point Transmitter is a digital dewpoint transmitter that continuously monitor air dryer performance, compressed air quality, and dry gas moisture from ambient dewpoint levels to as low as -100°C (-148°F). They are designed as compact, simple, and reliable instruments.
