The new gas monitor based on the Photoacoustic infrared detection method from Innova AirTech Instruments is now available with many new features.
Gas selectivity is achieved through the use of optical filters. The 1412 can have up to 6 filters installed, allowing for simultaneous measurement of the concentration of up to 5 component gases and water vapour in any air sample. The detection limit is gas dependent but is typically in the ppb region. The accuracy of measurements is ensured by the ability of the instrument to compensate for temperature and pressure fluctuations, water vapour interference and influences from other gases known to be present. The Photoacoustic measurement system requires no consumables, very little maintenance and recalibration only 12 times a year.
