Accredited calibrations

Calibrations guarantee precise and reliable results, determining the indication error of instruments and measuring systems. T.E.S.I. is an Accredia-accredited laboratory according to ISO/IEC standard 17025 to issue certificates in a wide range of physical measurements:

Calibration Report

The Calibration Report is issued when the centre is not accredited but has instrumentation traceable to national standards, expertise and procedures. Our Calibration Reports are issued for several measuring instruments, with high levels of accuracy, precision and reliability, in line with the requirements of ISO 9000 quality systems. The calibration process ends with the issue of a certificate with the measurement results, the instrument settings, the traceability chain and calibration uncertainty.

Calibration of energy meters for tax purposes

Legal metrology is the science of measurements related to commercial transactions. This includes the calibration for tax purposes of meters installed on electricity production plants for accurate and reliable consumption calculation oriented, for example, towards billing. Our centre has held accreditation since 2005 for the calibration of energy meter, both static and  electrodynamic, measuring transformers and measuring units.

Calibration of motor vehicle speedometers

We are the first Italian laboratory accredited for the calibration of motor vehicle speedometers in 2006 and for the calibration of Traffic light violation monitoring equipment in 2007. The experience gained in the various time lapse measurements has supported, since 2002, a series of studies and research on the calibration of these instruments to ensure the traceability of measurements to national samples, with a path that has culminated in the design and development of original, reliable and flexible systems. A further development is dated 2017 when we received the extension of accreditation to the calibration of the Length of Road Sections according to Ministerial Decree 282/2017 and Average vehicle speed measurement systems.
