Description The Xentaur digital dew point transmitter is a compact, simple, and dependable device that continuously monitors air dryer performance, compressed air quality, and dry gas moisture down to -100°C (-148°C) ambient dewpoint levels. The dew point transmitter is controlled by a menu-driven user interface that includes a customized LCD display with a backlight and four pushbuttons. The pushbuttons may be used to show a variety of various engineering units, including dew point in degrees Celsius, degrees Fahrenheit, ppmv, g H2O/M3, and pounds H2O/million scf.
