Brought to You With Passion. METTLER TOLEDO is the world's leading manufacturer of balances and a significant supplier of weights, weight sets and related weight calibration services. The weight portfolio covers ANSI/ASTM and OIML weights from one milligram to five tons in all accuracy classes.
Our weight portfolio covers weights according to OIML or ASTM from fifty micrograms to five tons in all accuracy classes. Our test weights are used all over the world, not only for testing balances but also as primary standards in mass laboratories.
Calibration Weights. Reference Weights, Mass Standards, Balance Calibration Weights, and Scale Weights & Test Weights adjusted to meet or exceed the tolerances for Troemner UltraClass, Class E0, Class 0, ASTM Class 1 to Class 7, OIML Class E1 to Class F2, and NIST Class F (replaced by ASTM Class 6).
Calibration and test weights are standardized masses certified by international, national, or industrial laboratories, such as NIST, ANSI, ASTM, or ISO. Each weight has a precise mass that makes it suitable for calibrating scales to ensure subsequent weight measurements are accurate.
Accurate metrological weights and weight sets with nominal mass values from 1 mg to 1,000 kg. Choose between wire weights and knob weights, as well as leaf weights, cylindrical weights and block shaped weights.
If you want to determine the balance error, it is relatively easy if you have a certified mass standard with the aforementioned data. With this information you should know how the weight performs plus or minus its associated uncertainty value.
