The Intrinsically Safe On-line Dew Point Analyzer COSA Xentaur XDT-NEMA is a compact, simple, and dependable instrument that is certified for usage in Class I Division II hazardous areas. The XDT-NEMA continuously monitors the operation of air dryers, compressed air quality, and dry gas moisture, from ambient dew points as low as -100oC (-148oF) to +20oC (+68oF).
Among those outstanding characteristics are hermetically sealed relays for use in hazardous areas Division II, an analog output, a 6-foot signal line, a power cable (specify connection), and a user’s manual. Additionally, it has analog and digital outputs for the RS 232 interfaces into the serial port of any PC or Mac, all of which are fully automated and prompt the user via a simple one-minute procedure and an error indicator.
