Model 910 Hot/Wet Multi Gas Mass Flow CEM



The AMETEK Process Instruments Model 910 is specifically configured for monitoring the stack emissions of multiple pollutants on a mass rate basis. It measures stack effluent temperature and velocity in addition to as many as five pollutant concentrations at stack conditions, enabling each pollutant’s mass emission rate to be reported. With the addition of an optional zirconium oxide sensor, the Model 910 is capable of monitoring oxygen.

The Model 910 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 910’s 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 Model 910 performs all necessary sample gas and calibration gas flow management, and probe and sample line temperature control. The Model 910 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.
