CALIBRATION SERVICE
Retroreflectometer calibration service
Proper calibration of your retroreflectometer is key to ensuring correct and repeatable measurements when testing pavement markings and road traffic signs for retroreflective performance.
The calibration reference requires regular calibration or renewal to function optimally
The retroreflectometer instruments LTL-M, LTL3000, LTL3500, LTL-XL, LTL-X Mark II, LTL2000-series, and RetroSign GR1, GR3 and GRX measure retroreflection characteristics of pavement markings and road traffic signs.
It is not sufficient to calibrate the instruments daily with the provided calibration reference to ensure their validity. You also need to have the calibration reference itself calibrated or renewed regularly, particularly if it is in frequent use or operates in harsh environments.
We recommend having your system calibration reference re-calibrated or renewed every two years or when the reference has become dirty beyond cleaning or damaged.
An accredited calibration with us guarantees calibration following international standards
We offer re-calibration services for all instruments. All re-calibrations or purchases of new calibration references are provided with a DANAK-accredited calibration certificate at no additional costs.
An accredited calibration guarantees calibration following quality criteria stated in our Calibration Quality Manual and in line with international standards for calibrations. Our DANAK-accredited calibration laboratory meets the ISO/IEC 17025:2018 requirements. DANAK certifies us for five years at a time and frequently undertakes control inspections during the certification period.
Our calibrations are accurate and can be traced back to international calibration bodies
The Danish Accreditation Body DANAK is a European Cooperation for Accreditation (EA) member. It ensures international recognition of calibration certificates drawn up by our Testing and Calibration Laboratory. Our calibrations can be traced to international calibration bodies like PTB (Physikalisch-Technische Bundesanstalt, Germany) and NIST (National Institute of Standards and Technology, USA). This is a guarantee for accuracy and the lowest possible uncertainty.
