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.
Conformance
Certifi cates of conformance can be supplied for new, serviced and recalibrated
instruments. These confi rm that instruments are within their original manufactured
specifi cation.
Service/Repairs
Regular servicing and any required repairs, under warranty or after, are available
from the Comark Service Department.
