The stable, durable PA4000 Photoacoustic Infrared Gas Monitor is purpose-built and detects minute amounts of a wide variety of gases. Three different enclosure styles ensure there is a configuration for wildly different situations. The instrument typically draws the gas sample via an internal pump, which allows the unit to be mounted in a convenient location if the area to be monitored is inaccessible. The unit can be expanded to monitor up to 8 locations, while an easy-to-read display shows gas concentrations and 3 levels of alarms.
