The INNOVA 3433i Photoacoustic Multi-Gas Monitor is a highly accurate, reliable and stable quanti-tative 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 3433i can measure the concentration of up to five component gases and water vapor in any air sample. Detec-tion limit is gas-dependent, but is typically in the ppb region.
The accuracy of these measurements is ensured by the 3433i’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 can be ensured by regular self tests. This measurement system requires no consumables and very little regular maintenance.
For most appli-cations, recalibration is only neces-sary one to two times a year.The monitoring system is easily operated through either the front panel, with its push-buttons and display providing short explanatory texts, or the PC software. Both inter-faces allow the user to configure the monitor, start a measurement sequence and view the resulting concentration values of specific gases.
The monitor is equipped with standard interfaces: USB, Ethernet and RS232. These enables the monitor to be integrated into automated process systems.To ensure easy placement of the 3433i, it is housed in a rugged box that fits in a standard 19 inches rack and has a built-in pump system that allows samples to be drawn from up to 50 meters away.
