continuous emissions monitoring device / air

THE NEED
A number of governmental air pollution regulations restrict the allowable stack emissions from various industrial facilities. Often, a facility will need to measure and report the emissions of a single pollutant being emitted by their process. Under many compliance regulations, it is not adequate to simply know the concentration of pollutants in the stack gas emissions. Often, a facility is required to monitor and report the mass emissions (e.g. lb/hr, kgs/day, etc.) of their processes.
In order to accurately monitor mass emissions, an analyzer must be capable of accurately and reliably measuring the pollutant of interest while simultaneously measuring the stack gas velocity. This feat is made all the more difficult as the stack gas is typically hot, saturated with moisture, and dirty.

THE SOLUTION
The AMETEK Western Research Model 909 is a single gas version of our Model 910 Continuous Emissions Monitor. The Model 909 is specifically configured for monitoring stack emissions on a mass rate basis. It measures stack effluent temperature and velocity in addition to pollutant concentration at stack conditions, enabling mass emission rates to be reported. With the addition of an optional zirconium oxide sensor, the Model 909 is capable of monitoring oxygen.
