MCERTS Certified Products: Indicative Ambient Particulate Monitors

Any potential user should ensure, in consultation with the manufacturer, that the CAMS is suitable for the application. It is important to refer to the details on certificates issued as they may contain specific limitations on use. The certificate holders listed have submitted satisfactory test reports and successfully undergone a product manufacturing audit.

The indicative dust monitoring analysers can be operated in one of two ways:

For qualitative measurements

Providing qualitative measurement data for the analysis of particulate pollution trends, and source identification studies based for example on pollution roses etc. Such application can rely on instrument factory calibration only.

For quantitative measurements

Providing measurement data with the uncertainty defined for indicative instruments (±50%), as specified by the Air Quality Directive (2008). This can be achieved on condition that each instrument used for measurement has been calibrated on the specific site where monitoring is taking place against a standard reference method for a period of two weeks and the resulting slope and intercept have been used for instrument calibration. Using non-standard filters and procedures for this purpose is not acceptable. To maintain the validity of data this calibration has to be repeated at least every twelve months or when the instrument is moved to a different site. Consistent results of the calibration may lead to less frequent repetition of the calibration process, in agreement with a competent authority, such as the Environment Agency or other Environmental regulator.
