MCERTS
MCERTS is the UK Environment Agency's Monitoring Certification Scheme. The scheme provides a framework
within which environmental measurements can be made in accordance with the Agency's quality requirements.
The scheme covers a range of monitoring, sampling and inspection activities.
Note: MCERTS - Cross sensitivity tests using hydrogen sulphide were not carried out on this instrument,
therefore, users should be aware if H
2
S is present on sites, as there may be an interferential effect.
MCERTS promotes public confidence in monitoring data and provides industry with a proven framework for
choosing monitoring systems and services that meet the Environment Agency's performance requirements.
The Environment Agency has established its Monitoring Certification Scheme (MCERTS) to deliver quality
environmental measurements. The MCERTS product certification scheme provides for the certification of
products according to Environment Agency performance standards, based on relevant CEN, ISO and national
standards.
MCERTS certified instruments have been tested by an independent body to ensure that they meet certain
performance requirements. In addition, the manufacturer of an MCERTS product is regularly audited to ensure
that the performance requirements of the certification are being continually met.
The 5000 series of gas analysers have been certified to Version 3.1 of the ‘Performance Standards for Portable
Emission Monitoring Systems’.
