Calibration is required in the process of controlling our equipment if we are to ensure the traceability of measurements.

With the help of etalon weights we verify the accuracy of our indication, eccentricity and repetability.

SERVICE
- We provide service of measuring devices of all types.
- For you we obtain an authorized service person.
WHY PERFORM CALIBRATION OF MEASURING DEVICES
- Change in temperature, humidity, air pressure and other adverse factors influence the accuracy of devices, as well as operator’s work.
- Accuracy of measuring devices is not stable time-wise.
- Regular calibration ensures accurate and precise operation of measuring devices.
- Indication accuracy and reproducibility are verified by reference values.
Certificate, which you are provided with after each calibration, ensure measuring traceability of measuring devices with establishment and maintenance of quality systems (ISO certification), laboratory accreditation and is in accordance with requirements GMP, GLP and GCP.
CALIBRATION PERIOD
Calibration period is set in accordance with standards or recommendations for ensuring quality of measuring equipment SIST ISO 10012, ILAC-G24 / OIML D10.
