Innova 1412i Photoacoustic Field Gas Monitor

The Photoacoustic Gas Monitor - INNOVA 1412i is a highly accurate, reliable, stable, quantitative and remote controllable 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 1412i, 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 1412i'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 1412i performs. By the nature of this measurement system, it requires no consumables and very little regular maintenance. For most applications recalibration is only necessary one or two times a year.

  • Selectively measures a wide range of gases/vapors
  • Linear response over a wide dynamic range
  • High Stability means a maximum of only two calibrations a year
  • User-friendly: Easy calibration, configuration, and analysis of data on PC
  • 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
  • Expandable up to 24 locations with 1409 Multipoint Sampler: the Gas Monitor can operate as the system controller for full standalone operation
  • Remote control capability via TCP/IP network interface protocol
