Weights

METTLER TOLEDO offers a comprehensive selection of weights, from 1 mg to 5 tons in all common nominal values and weight classes.

While national laboratories trust our unmatched reputation for highest classified weights used as reference standards, customers in all industries use our weights for calibration and routine testing of balances and scales. Related calibration services are offered through one of our ISO 17025 accredited Mass Laboratories, building a global network with short re-calibration times.

METTLER TOLEDO is a professional supplier of weights, weight sets and related weight calibration services. The weight portfolio covers weights according OIML, ASTM and NIST from 1 mg up to several tons in all accuracy classes.

Innovation of METTLER TOLEDO weights

Vacuum melted steel for highest level of material purity
Vacuum melting of steel ensures consistently high quality by reducing undesired trace elements, removing dissolved gases and improving oxide cleanliness.

Unique weight adjustment procedure
Electrolytic adjustment is a unique technique developed by METTLER TOLEDO to achieve surface roughness that far exceeds the required specifications.

Initial weight calibration performed by robots
Substantial investments in cutting-edge robot technology combined with decades of experience have opened up a new field in weight calibration. Computer-controlled processes eliminate any human errors, and lead to consistent and reproducible results with low uncertainty values.

Routine testing
Increasing accuracy and minimizing risk. Systematic testing of balances and scales minimizes risks and reduces costs. Under the GWP^® program METTLER TOLEDO recommends using only two weights for routine testing.
