The Photoacoustic Gas Monitor - Innova 1512 selectivity measures a wide range of gases/vapors.

The selecitivity is achieved trough 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.

The accuracy of the measurements is ensured by the 1512 ability to compensate for temperature and pressure fluctuations, water vapor interference, and inferference from other known gases in the sample air.

Detection limits are gas dependent, but typically in the ppb range.

The type 1512 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 1512 can also be used with a type 1403 Multipoint sampler and Doser, to preform ventilation and air exchange measurements with the 7650 software, and enabling all tracer gas methods: Concentration decay, Constant injection and Constant concentration with 7651 software, both using a tracer gas.
