Photoacoustic Gas Monitor
The PA4000 Photoacoustic infrared gas monitor from General Monitors provides gas monitoring while eliminating interference from water vapors. The monitor is designed with an advanced photoacoustic, infrared (IR) sensor to monitor a variety of gases including hydrocarbons, solvents, alcohols, CO2, CO and other dangerous gases. Can operate for months with virtually no drift. It features a proprietary sensing technique that determines the amount of water vapor in the sample and subtracts it from the gas reading. This technique allows the gas reading to be stable with no compromise to measurement sensitivity. With a range of 0-1000 ppm depending on the specific configuration, the PA4000 Gas Monitor is accurate to ± 2 ppm at 0-100 ppm and ± 10% of reading from 100-1000 ppm. The PA4000 features sensitivity of 2 ppm and resolution of 1 ppm, with specifications for other ranges dependent on application. For certain gases, it detects concentrations as low as 0.01 ppm.
