GENERAL INFORMATION
It is recommended that you read the safety and operation instructions
before using this instrument.
TO AVOID ELECTRIC SHOCK DO NOT ALLOW ANY PROBE OR
WARNING
SENSOR TO COME INTO CONTACT WITH LIVE ELECTRICAL
POWER CONDUCTORS WITH VOLTAGES IN EXCESS OF 30V AC
RMS OR 60V DC.
CAUTION
Temperature Measurement Probes
This precision instrument has been designed for use with the extensive
range of Comark temperature probes. The use of other probes may
impair the performance and accuracy of the instrument. Full details of
Comark probes and sensors can be obtained from Comark Customer
Support department or your local distributor.
Repeated sharp exing can break thermocouple probe leads. To
prolong lead life, avoid sharp bends or kinks in the leads, especially
near the connector.
This instrument is manufactured in accordance with
the Company’s ISO 9001 Quality Approved
System.
ISO 9001
FM 29700
This instrument complies with the Electromagnetic
Compatibility Directive EN 61326-1.

CALIBRATION, CERTIFICATION AND SERVICE
Certication
Comark can provide certicates of calibration for its whole product range, to suit
ISO 9000 and other quality assurance procedures, food hygiene regulations,
HACCPs and environmental regulations. Comark certicates 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 certication/recalibration.
Two levels of certication are available for infra-red temperature and non
temperature instruments, excluding humidity:- UKAS certicates via an external
accredited laboratory and NPL traceable certicates from the Comark calibration
laboratory.
Three levels of certication are available for contact temperature and humidity
products and these are detailed here:
a) UKAS Temperature Certication
The Comark UKAS (United Kingdom Accreditation Service) accredited
temperature calibration laboratory is one of the nest in the UK. Comark
UKAS certicates 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 Certication
In addition to the Comark temperature laboratory, the humidity laboratory
continues the tradition of high accuracy certication 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 Certication
Comark NPL certicates are traceable to the National Physical
Laboratory and can offer uncertainty as low as 0.3°C.
No. 0451
Conformance
Certicates of conformance can be supplied for new, serviced and recalibrated
instruments. These conrm that instruments are within their original manufactured
specication.
Service/Repairs
Regular servicing and any required repairs, under warranty or after, are available
from the Comark Service Department.
For more information on all Comark certication, calibration and service facilities
please call Comark Customer Support or contact your local distributor.
