Accurate and stable reference standards for calibrating weighing equipment, including variously certified/accredited weights and weight sets from different classes. Products may be constructed of aluminum, stainless steel, brass, iron, and other alloys.

Calibration weights (also known as reference weights or test weights) are manufactured to meet high tolerances and accuracy. They are used to spot-check the performance and verify the calibration of analytical balances, precision balances, and general-purpose scales in research laboratories, educational settings, and other working environments.

Principal Classes of Calibration Weights:

• Class M1: For standard scales
• Class F1: For precision electronic balances
• Class E2: For highly accurate analytical balances

We offer you reliable and accurate service for all your weights calibration needs. We can perform weights calibrations on as per OIML clarifications:

• Class F1 & Class F2: standard weights
• Class M1 & Class M2: Industrial weights

If you need any other calibration related to weights, please contact head of the Mass Laboratory prabath@slsi.lk or contact on +94 112 67 1567 ext 563/263
