Calibration


In order to achieve quantitative measurement output (mg/m3) from PCME sensors and to ensure optimum performance from PCME's Particulate Monitoring Systems, it is necessary that the unit is calibrated against the results from the standard reference method (SRM), via isokinetic sampling.

To obtain the most accurate calibration there are a number of steps to follow and PCME are pleased to assist you with all these stages, as detailed below. PCME's Calibration service is in full accordance with the most recent guidance from the Environment Agency (RM-QG6) as issued in September 2009.

Commitment to effective calibration procedures will also assist with increased OMA Audit scores, as detailed in OMA Guidance - air, OMA - 3, in the Environment Agency's document "Guidance on undertaking an Operator Monitoring Assessment of emissions to air and/or water" Version 3, April 2009.

It is recommended that in most applications, calibration on an annual basis is suitable and sufficient, however, there may be instances where more frequent or multiple calibration exercises are required, such as due to periodic process changes. PCME will advise on the most suitable regime that is required.

For international clients PCME would recommend calibration to international or national standards and as a minimum our dust monitors should be calibrated annually.  Please consult PCME or your local supplier for further details.
