Innova 1412 Photoacoustic Field Gas Detector

The Photoacoustic Field Gas-Monitor - INNOVA 1412 is a highly accurate, reliable and stable quantitative gas monitoring system. It uses a measurement system based on the photoacoustic infrared detection method, and is capable of measuring almost any gas that absorbs infrared light.

Gas selectivity is achieved through the use of optical filters. By installing up to five of these filters in the 1412, it can measure the concentration of up to five component gases and water vapor in any air sample. Although the detection limit is gas-dependent, it is typically in the ppb region. The accuracy of these measurements is ensured by the 1412's ability to compensate for temperature and pressure fluctuations, water vapor interference and interference from other gases known to be present. Reliability of measurement results is ensured by regular self tests, which the 1412 performs. By the nature of this measurement system, it requires no consumables and very little regular maintenance, for example, for most applications recalibration is only necessary one - two times a year.

  • Selectively measures a wide range of gases/vapors
  • Linear response over a wide dynamic range
  • High stability (low drift) makes calibration only necessary one - two times a year
  • Extremely reliable due to self-testing procedures
  • User-friendly procedures for calibrating the monitor, presenting and analyzing measurement data via the PC user interface
  • Accurate - compensates for temperature and pressure fluctuations, water vapor interference and interference from other known gases
  • Extremely low-volume flushing possible
  • Operates immediately - almost no warm-up time necessary
  • Presents measurement data via connected PC both in tabular and graphic formats - up to five gas concentration and water vapor graphs displayed, simultaneously
