Automotive Emissions Monitor
The Automotive Emissions Monitor - 3433i is a highly accurate and reliable Multi Gas Monitor based on the INNOVA 1314i platform with special configuration for Exhaust Gas or SHED Evaporative Emissions Testing.
Its measurement principle is based on the photoacoustic detection method. In addition to its high sensitivity for multiple trace pollutant monitoring, the model 3433i is valued for its extremely simple integration into most test installations and for enabling reliable direct measurements.
Gas selectivity is achieved through the use of optical filters with narrow bandwidth. By installing up to 5 optical filters in the INNOVA 3433i, it can measure the concentration of up to 5 component gases and water vapor in any air sample. Detection limit is gas-dependent, but is typically in the ppb region. The accuracy of measurements is ensured by the INNOVA 3433i's ability to compensate for temperature and pressure fluctuations, water-vapor interference and interference from other gases known to be present (Cross-compensation). Reliability of measurement results is ensured by regular, automatic self-tests.
