ProAir 2200 is a compact, easy to install and operate compressed airline monitor that can continuously and simultaneously monitor up to four gases in real-time using internally mounted sensors. ProAir 2200 can be custom configured to monitor a variety of hazardous gases present in compressed air, including carbon monoxide, oxygen, dew point, carbon dioxide, VOCs, trace hydrocarbons and many other gases associated with OSHA monitoring requirements for Grade D breathing air.

ProAir 2200 has a user-friendly software interface and is operated by using push buttons and LCD display. The general instrument set-up configuration and maintenance functions are password protected to prevent unauthorized personnel from gaining access to secure data. The maintenance and operation menu functions allow the user to change alarm points, program relays and perform calibrations in the field. The monitor uses a backlit digital display, a power LED and a fault LED indicator, integrated audible and visual alarms with two alarm threshold indicators and features a four minute audio defeat option for alerts below alarm level maximum. The sample inlet pressure must be regulated to 55 psi. It has an integral electronic flow sensor with a fault alarm to monitor for low flow conditions of less than 0.2 liter per minute.
