920 Hot / Wet Multi Gas Analyzer 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.
A very robust and reliable analyzer, UV-based measurements do not suffer from H2O and CO2 interference. They can also have a wide dynamic range for some measurements. Greatly simplifies sample handling and sample integrity, 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. Results are a simpler and more accurate calculation of gas concentrations., requiring no corrections for condensed and dissolved components.
