Calibration, recalibration of weights and masses
COFRAC calibration certificate – CEI 17025 / Mass accreditation 2-1218 Scope available on www.cofrac.fr
Calibration of new weights and masses : E1, E2, F1, F2, M1, M2, M3
Since 1991, we ensure the maintenance of weights and masses over time. Zwiebel is able to support you for all your bespoke projects. According to the nominal value and accuracy of the weight class, calibration is managed in one of our three laboratories.
What does accreditation implies ? NF EN ISO/CEI 17025
Accreditation is an acknowledgement that a laboratory conducts calibration in a defined field with specified uncertainties.
In our laboratories, we use precision equipment and stringent methods and employ skilled personnel to calibrate the weights and masses.
With an extremely fine resolution – from 0.1 microgram to 1 gram – the manual comparators and automated systems we use are the guarantee of excellent service.
Calibration documents are available in English, German, Italian, Portuguese and Spanish.
Recalibration of new weights and masses E1, E2, F1, F2, M1, M2, M3.
We ensure the maintenance of weights and masses over time. Indeed, by recalibrating your weights in our laboratories, you can control developments and, if need be, request the manufacturer to adjust or repair them. Zwiebel is able to recalibrate all kind of weights and masses which nominal values comprise between 1mg and 2t according to its COFRAC (Mass accreditation 2-1218 Scope available on www.cofrac.fr) range accreditation.
Recalibration periodi is usually every 1 to 3 years. It can be reschedule according to the results registered between 2 calibrations, but weight owner is still the decision maker for this.
