WHY PERFORM CALIBRATION
- Changes in temperature, humidity, air pressure and other adverse factors influence weighing accuracy, as well as operator’s work.
- Constant use represents wear of measuring devices and therefore change in value.
- Accuracy of measuring devices is not stable time-wise.
- Regular calibration ensures accurate and precise operation of measuring devices.
- At calibration, cleaning and setting of measuring devices is performed.
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.
