Calibration Weights:
Single Calibration Weights & Weight Sets

↓ jump down to products ↓

We carry a wide variety of calibration weights and calibration weight sets in several classes. Use these calibration weights to calibrate an inaccurate scale, or just to make sure your scale is “right on the money”. We have a good range of masses in weight tolerance classes OIML E2, OIML F1, OIML M2, and ASTM classes 0, 1, 2, 3, 4 and 6.

If you're here for just a single weight, narrow your results by choosing the single calibration weight subcategory below. If ya need more than one weight, ya might save some money by choosing a set of calibration weights. They have their own subcategory, too.
