MCERTS instrument testing
Gas Detection / Calibration
Information
NPL has developed a dedicated suite of test and calibration facilities that are accredited under ISO 17025. These are used for carrying out instrument tests to the MCERTS Performance Standards and Test Procedures for Continuous Emission Monitoring Systems and EN 15267-3, together with Performance Standards for Continuous Ambient Air Quality Monitoring Systems, including EN 14662-3. The state-of-the-art facilities include:
1. Variable temperature test cells that can operate up to 400 ºC, where accurate concentrations of stack gases and water vapour can be introduced to simulate stack conditions.
2. A patented gas dilution system that is used to generate a wide range of required gas concentrations.
3. An environmental chamber for testing those parts of the monitoring system exposed to outdoor conditions.
4. The ability to test two instruments in parallel, including cross duct and extractive instruments.
NPL can also carry out field tests for MCERTS and are accredited for the requirements of BS EN 15267-3, ISO 17025 and BS EN 14181. We have the capability and accreditation to measure a wide range of combustion gases, including HCl, N2O, SO2, CO, CO2, NO, NO2, VOCs and O2 to CEN and ISO standards. NPL's emissions monitoring teams have a wealth of experience and work closely with clients to provide assurance that the monitoring and data provided is accurate and reliable, and the reports have the information to meet all requirements of the MCERTS Performance Standard.
