The Photoacoustic Gas Monitor -Innova 1412i Selectively measures a wide range of gases/vapors.
The selectivity is achieved through the use of optical filters.
By installing up to five filters the 1412i can measure the concentration of up to five component gases and water vapor.
The accuracy of the measurements is ensured by the 1412i's ability to compensate for temperature and pressure fluctuations, water vapor interference, and interference from other known gases in the air sample.
Detection limits are gas dependent but typically in the ppb range .
The Type 1412i can be combined with a Type 1409 Multipoint Sampler using the 7880 software to extend the capability by delivering air samples from up to 24 measurement locations.
The Type 1412i can be used with a Type 1403 Multipoint Sampler and Doser to perform ventilation and air exchange measurements with 7650 software, and Enabling all tracer gas methods: Concentration decay, Constant injection and Constant concentration with 7651 software, both using a tracer gas.
