The Edgetech Com.Air is a dedicated dew point monitor engineered for reliable and maintenance-light operation in compressed air systems. It utilizes a highly accurate chilled mirror sensor to deliver consistent, drift-free measurements without the need for regular calibrations or sensor replacements, a significant advantage over other sensing technologies .

A key feature contributing to its low maintenance is the programmable Automatic Balance Control (ABC) cycle . This system automatically corrects for the light-reducing effects of mirror contaminants, re-standardizing the instrument and allowing for virtually maintenance-free, continuous monitoring. An 8-digit alphanumeric display ensures easy readability.

The Com.Air is designed for straightforward installation and use. It is housed in a rugged aluminum NEMA-12 enclosure that contains the sensor, control circuitry, flow control, and flow meter; only sample line and power connections are needed to begin operation. The monitor provides a 4-20 mA analog output, an RS-232 serial output, and a comprehensive alarm system including audible and visual alerts and a Form C alarm relay. This makes it an ideal choice for ensuring the quality of instrument air, dry air for critical processes, and other applications requiring dependable dew point monitoring.
