Frequently Asked Questions

If not following regulations for maintenance or calibration frequency, we suggest defining maintenance frequency based on the risk of the particular application. This means the higher the risk the more often the balance should be calibrated and maintained. A general recommendation is to perform a calibration and maintenance at least once per year. 

Calibration is the comparison of a measured value with a known, i.e., correct, value. For example, during calibration of laboratory balances, the indications shown on the display are compared with known test weights. The documented values, as well as the values calculated (e.g., deviation, uncertainty of measurement), represent the calibration result.

A laboratory accredited for compliance with ISO 17025 has demonstrated the quality of its calibration data to an independent accreditation body, such as UKAS in the U.K., ANAB in the USA or DAkkS in Germany. Calibration certificates issued by accredited laboratories offer the highest possible degree of reliability and are recognized worldwide.

A measuring instrument is considered to deliver traceable results if they are referenced to a national or an international standard through an unbroken chain of comparisons, all having stated uncertainties. Therefore, verification of traceability ensures international comparability and, thus, the reliability of measurement results.

Important information: In many countries, only accredited calibration certificates or certificates issued by national metrology institutes are accepted as evidence of metrological traceability. No other calibration certificates (e.g., ISO calibration certificates or verification certificates) are valid as forms of evidence. For further information, visit International Laboratory Accreditation Cooperation.

The uncertainty of measurement provides reliable information about the quality of a measurement result. It indicates the range of values in which the true measured value lies. The lower the uncertainty of measurement, the narrower the range within which the true value lies. Accredited calibration certificates issued by Sartorius state the uncertainty of measurement in an easy-to understand way and provide confidence in interpreting your measured values.

The service interval is defined in your contract. Before your next maintenance date, we will first contact you in writing and then call you to schedule an appointment.

Please contact Sartorius service. Use our contact form and provide us with as many details as possible so that we can help you quickly.
