The 920 is specifically configured for monitoring the stack emissions of multiple pollutants on a concentration basis. It measures as many as five pollutants at stack conditions. With the addition of an optional zirconium oxide sensor, the 920 is capable of monitoring oxygen.
The 920 is a very robust and reliable analyzer. Its UV-based measurements do not suffer from H2O and CO2 interference. They can also have a wide dynamic range for some measurements. This greatly simplifies sample handling and sample integrity as there is no need for sample drying. As a fully extractive, heated wet basis analyzer, the 920s sample system components are simply heated above the dew point of the sample gas. This results in a simpler and more accurate calculation of gas concentrations, requiring no corrections for condensed and dissolved components.
The 920 performs all necessary sample gas and calibration gas flow management, and probe and sample line temperature control. The 920 is a full function Continuous Emissions Monitoring System (CEM) which requires the addition of only a sample probe and sample line to be fully operational. Housing options for the analyzer include a cabinet or walk in shelter built to your specifications.
