Test Weights (Laboratory)

Mettler Toledo expertly manufactured weights are used in various application areas. They enable efficient and effective routine testing of weighing instruments, reliable balance and scale calibration or accurate and traceable calibration of reference weights. Choose from 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.

In the design of knob weights, their stainless steel test weights are available with and without adjusting cavities as well as wire or sheet weights in the milligram range.  They are produced from the finest quality austenitic steel which offers the highest resistance to corrosion over a weight’s lifetime. Mettler Toledo’s unique manufacturing process involves melting the steel under vacuum (class E1), final-stage electrolytic polishing, fully automated cleaning processes, and final calibration using our mass comparators.
