New release: Photoacoustic infrared gas monitor

0

General Monitors, a global specialist in gas monitoring and flame detection instrumentation has released a new infrared analyser with cross-sensitivity to water vapour.

The PA4000 Photoacoustic Infrared Gas Monitor eliminates interference from water vapours. It has been designed with a photoacoustic infrared sensor designed to monitor various gases including hydrocarbons, solvents, alcohols, CO2, CO and other dangerous gases. According to the manufacturer, the device is stable and highly selective to individual gases, while it also boasts several months operation without drift.

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.

The PA4000 Gas Monitor eliminates a problem common to infrared analysers: cross-sensitivity to water vapour. It features a proprietary sensing technique that determines the amount of water vapour in the sample and subtracts it from the gas reading. This technique allows the gas reading to be stable as well as sensitive.
