Services
Verification of measuring instruments
We offer the following services based on our own metrological service:
- calibration of measuring instruments
Our metrological service is accredited for the right to initial and periodic verification of measuring instruments
The required number of standards and auxiliary equipment, premises and regulatory documents;
Its staff consists of highly qualified specialists.
According to the results of verification, a certificate of a standard form is issued, valid throughout the territory of the Russian Federation. The verification certificate form is protected against counterfeiting by watermarks and a holographic sticker with a unique number.
At the request of the customer, according to the results of verification, along with the certificate, a verification protocol can be issued.
The accreditation area includes measuring systems containing components that are part of this accreditation area
The timing of verification work does not exceed two weeks from the date of acceptance of the equipment and the letter of guarantee. By additional agreement, urgent work is possible
At the request of the customer, an agreement is drawn up for the provision of calibration services for measuring instruments
The execution of the Agreement or letter of guarantee may be preceded by a request by the Customer for a commercial offer for the performance of work.
