Low Annual Operation Cost
The PureAire Air Check Advantage Carbonyl Sulfide Monitor has a built-in, low-power pyrolizer, and long-life sample pump.
Connects to DCS and PLC Controls
The Air Check Advantage Carbonyl Sulfide Monitor transmits continuous gas concentration levels to any distributive control system, programmable logic controller, or PureAire’s proprietary single and multichannel controllers. The monitor can operate up to 1,000 meters, 0.6 miles from centralized distributive control systems.
