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 GEM2000 Plus has been certified to Version
1 of the ‘Performance Standards for Portable
Emission Monitoring Systems’.

Over range codes
Over range codes are the symbols displayed to
signify an event where the reading obtained is
above the full scale of the particular channel.
The symbols used for this event are ‘greater
than’ chevrons in the following formats (>>.>
or >>>>).
Particulate filter
Also referred to as the Inlet Port Filter. The
particulate filter is located on the underside of
the instrument and is accessed by removing the
plastic plug. Its purpose is to stop any particles
entering the instrument.
Never operate the instrument without the
particulate filter.
When replacing the plug be sure not to over
tighten it - finger tight is adequate.
