MCERTS promotes public confidence in monitoring data and provides industry with a proven framework for choosing monitoring systems and services that meet Environment Agency requirements. More recently, the Continuous Emission Monitoring Systems (CEMS) standard has been updated to include new requirements and specifications for transportable monitoring equipment - as can be seen in Annex F. A transportable system is a variant of a CEM designed for periodic use, typically on more than one stack, rather than fixed emissions monitoring. Transportable systems have two main applications; for use within SRMs, or as back-up CEMS. The testing requirements differ depending what application the product fits into. For use as a back-up CEM, field test data is essential. Some portable systems are variants of fixed CEMS, designed to the same high standards, suitable for measuring emissions close to emissions limit values and for calibrating CEMS. These systems are covered by the transportable annex of the CEMS standard, rather than the portable emissions standard.
