Services

Verification of measuring instruments

"VXI-Systems" Ltd. offers the following services on the basis of its own metrological service:

  • Verification of measuring instruments
  • Calibration of measuring instruments

Metrological service of "VXI-Systems" Ltd. is accredited for the right of primary and periodic verification of measuring instruments

* Accreditation certificate in the field of ensuring the uniformity of measurements № РОСС RU.0001.310103 from 25 December 2012

In accordance with the scope of accreditation, the service is equipped with:

  • The necessary number of standards and auxiliary equipment, premises and regulatory documents;
  • It employs highly qualified specialists, certified as trustees.

As a result of verification, a certificate of the established type is issued, valid throughout the territory of the Russian Federation. The verification certificate form is protected from forgery by watermarks and a holographic sticker with a unique number.

  • At the request of the customer, verification results can be issued together with the certificate based on the verification results.
  • During calibration, the customer must receive a protocol with all the metrological characteristics set according to the calibration method.
