These are a series of lightweight, highly sensitive instruments, based on a novel surface chemiluminescence.

Suited for indoor and outdoor monitoring and ideal for applications where battery operations and lightweight mobility are required, such as on aircraft.

The principle of operations is very simple. The sample air is drawn through the instrument by a micro pump and flows across a fabric wick wetted with a prescribed solution. The solution is continuously replenished at the top of the wick and removed at the bottom by a liquid mass flow system. Surface reaction of the monitored gas results in chemiluminescence. The resultant signal from the photomultiplier is directly proportional to the mixing ratio of the gas in the air.
