CALIBRATION, CERTIFICATION AND SERVICE
Certifi cation
Comark can provide certifi cates of calibration for its whole product
range, to suit ISO 9000 and other quality assurance procedures, food
hygiene regulations, HACCPs and environmental regulations. Comark
certifi cates are produced by independent quality controlled processes
which compare product performance against agreed National
Standards. For peace of mind and best practice Comark recommend
annual certifi cation/recalibration.
Two levels of certifi cation are available for infra-red temperature and
non temperature instruments, excluding humidity:- UKAS certifi cates via
an external accredited laboratory and NPL traceable certifi cates from
the Comark calibration laboratory.
Three levels of certifi cation are available for contact temperature and
humidity products and these are detailed here:
a) UKAS Temperature Certifi cation
The Comark UKAS (United Kingdom Accreditation Service)
accredited temperature calibration laboratory is one of the
fi nest in the UK. Comark UKAS certifi cates 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
National Physical Laboratory.
b) UKAS Humidity Certifi cation
In addition to the Comark temperature laboratory, the humidity
laboratory continues the tradition of high accuracy certifi cation
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 Certifi cation
Comark NPL certifi cates are traceable to the National Physical
Laboratory and can offer uncertainty as low as 0.3°C.
