Test weights, weight sets and weight calibration services for balances and scales. Highly efficient and effective for routine testing of weighing instruments, calibration of balances and scales, or accurate and traceable calibration of reference weights. Choose either OIML or ASTM test weights to check the performance of your weighing device in the range from 50 micrograms to five tons in all accuracy classes, with or without a calibration certificate.

To ensure accurate routine performance testing and reliable calibration of balances and scales, as well as to serve as primary standards in mass laboratories, it is essential to use test weights, weight sets, and calibration weights. These weights are categorized into tolerance limits according to OIML or ASTM standards, ranging from 50 mg to 5 tons across all accuracy classes.
METTLER TOLEDO offers a wide range of test weights made from corrosion-resistant stainless steel. Their electrolytic polishing process for knob and wire weights removes tiny protrusions, resulting in a glossy, anti-adhesion finish. A passive oxide film is created on the test weight, enhancing long-term stability. Weight sets range from 1 mg to 500 mg and up to 1 mg to 5 kg, with or without a calibration certificate. Balances can be securely tested according to USP General Chapter 41 using just two test weights to assess 5% and 100% of the balance capacity. The CarePac® includes gloves, tweezers, and other necessary accessories.
