Calibration Weight Sets (Old and Stored)

Calibration Weights sets, typically designated for laboratories or facilities. • The label on the box reads: ‏“Class 5 Weights – Range 5g … 100g” This indicates that the weights are classified as Class 5 according to international standards (OIML – International Organization of Legal Metrology). ‏Class 5 means these are calibration weights with medium accuracy, suitable for regular scales or laboratory balances that do not require extremely high precision (higher precision would be Class 1 or Class 2, intended for highly accurate laboratories). • Contents: The box contains weights ranging from 5 grams to 100 grams, usually made of stainless steel. The weights in the set include: 5g, 10g, 20g, 50g, 100g. It also includes a yellow plastic tweezer to avoid touching the weights directly with hands (since hand heat and oils can alter the weight precisely by fractions of a milligram). • Uses: 1- Calibrating mechanical and electronic scales. 2- Scientific experiments in schools or universities. 3- Industrial laboratories requiring adjustment of sensitive balances. • Price: 250 SAR 💵.
