The Flexibility & Versatility of a Portable Emissions Analyzer

Application Note #IA-13-0501


Fixed CEMS (Continuous Emissions Monitors) Measure at One Location

CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.

If the CEM is measuring emissions that are higher than the regulated or permitted limits, it can be difficult to determine the source of the high emissions which could be from any or several of the separate sources that feed into the main stack.


Measure with a Portable Emissions Analyzer

The customer can measure from any of the smaller stacks that feed into a main stack or from any emissions source throughout the plant with a portable emissions analyzer. A portable analyzer provides more flexibility and versatility than a CEM in terms of the multiple locations it can be used throughout the plant and how it can measure from different emissions sources.

Using a portable emissions analyzer can help to quickly and more precisely determine sources of high emissions and inefficient or unsafe equipment performance.
