Weights

RANGE

• from 1 mg to 500 kg

• Accuracy class weights:
  • E2: from 1mg to 500g
  • F1 and F2: from 1mg to 20kg
  • M1, M2 and M3: from 1mg to 50kg
  • M1-2 and M2-3: 500kg

• Objects from other optional masses:  to 400kg

WE PERFORM

• Calibration of weights in accordance with recommendation OIML R111 - 1.
• Execution in our laboratory (or on-site – for accuracy classes M).

USE

• As etalon value at weights calibration,
• as etalon value at scales calibration,
• for daily control of scales,
• for weighing on double dish mechanical scales,
• where appropriate traceability of mass measuring devices needs to be ensured,
• where scale accuracy need to be ensured on a daily basis.

Limits the maximum allowable weight deviations from the nominal value of weights in accordance with international standards OIML R111

ADJUSTMENT

• We perform adjustment of weights of all types – if construction-wise possible.
   

WHY PERFORM CALIBRATION

• During work and storage, weight can be magnetized,
• mass of weights is not stable time-wise,
• use of weights affects their accuracy,
• with given range, we ensure uncertainty of measurement of 1/3 of maximum allowable error,
• daily control of scales is performed with weight, for which we know their accuracy and uncertainty of measurement of weights.

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.
