CALIBRATION, CERTIFICATION AND SERVICE
Certification
Comark can provide certificates of calibration for its whole product
range, to suit ISO 9000 and other quality assurance procedures, food
hygiene regulations, HACCPs and environmental regulations. Comark
certificates are produced by independent quality controlled processes
which compare product performance against agreed National Stan-
dards. For peace of mind and best practice Comark recommend annual
certification/recalibration.
Two levels of certification are available for infra-red temperature and
non temperature instruments, excluding humidity:- UKAS certificates via
an external accredited laboratory and NPL traceable certificates from
the Comark calibration laboratory.
Three levels of certification are available for contact temperature and
humidity products and these are detailed here:
a) UKAS Temperature Certification
The Comark UKAS (United Kingdom Accreditation Service)
accredited temperature calibration laboratory is one of the fin-
est in the UK. Comark UKAS certificates can offer the lowest
uncertainty of 0.01°C and provide independent proof of correct
calibration using equipment and procedures audited by UKAS
inspectors. The equipment used is fully traceable to the Na-
tional Physical Laboratory.
b) UKAS Humidity Certification
In addition to the Comark temperature laboratory, the humidity
laboratory continues the tradition of high accuracy certification
and a wide range (25% to 90%RH) with uncertainties of 2.8% of
reading. This range also includes Dew point measurements.
c) NPL Traceable Certification
Comark NPL certificates are traceable to the National Physical
Laboratory and can offer uncertainty as low as 0.3°C.
Conformance
Certificates of conformance can be supplied for new, serviced and
recalibrated instruments. These confirm that instruments are within their
original manufactured specification.
