Highly Accurate, Stable, Quantitative, and Remotely Controllable Gas Monitoring System
Advanced Energy's Innova 1512 is based on the photoacoustic infrared spectroscopy and delivers superior sensitivity in a very compact form factor. Extremely versatile by design, the 1512 is capable of measuring almost any gas that absorbs infrared light.
It is a highly accurate, reliable, and stable quantitative gas monitoring system. Its measurement system, based on the photoacoustic infrared detection method, 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 filters, the 1512 can measure the concentration of up to five component gases and water vapor in any air sample. The detection limit is gas-dependent, but is typically in the ppb region. Accuracy of these measurements is ensured by the 1512’s ability to compensate for temperature and pressure fluctuations, water vapor interference, and interference from other gases known to be present.

stored in the gas monitor's internal memories
Gas dependent, but typically in the ppb region; using the Gas Detection Limits Chart, the detection limit for a selected sample integration time (SIT) can be calculated
Typically four orders of magnitude (i.e., 10,000 times the detection limit at 5 SIT); using two span concentrations it can be expanded to five orders of magnitude
1% of measured value
Measured at 20°C, 1013 mbar, and relative humidity (RH): 60%; a concentration of 100x detection limit (5s SIT) was used in determining these specifications
The 1512 automatically compensates for temperature and pressure fluctuations in its analysis cell and can compensate for water vapor in the air sample; if an optical filter is installed to measure a known interferent, the 1512 can cross compensate for the interferent.
