At True-Precision, you can purchase calibration weights in all shapes and sizes. Calibration certificates are available for nearly all weights, ensuring they meet your internal standards. Most of our calibration weights come from the renowned German manufacturer KERN & SOHN, which has the certified equipment required to calibrate and issue official calibration certificates.

We offer weights made from a variety of materials, including stainless steel and aluminum. You’ll also find different surface finishes – some weights have a highly polished, smooth surface, which is essential for high-precision applications, while others have a rougher finish, suitable for less sensitive tasks where minor deviations in milligrams are not critical.

Our calibration weights range from as small as 1 mg up to 50 kg. Many of the smallest weights come with a protective case to ensure accuracy is maintained. For larger weights, a case is usually not included but can be purchased separately if needed.
