Weights are available in OIML classes E1, E2, F1, F2, M1, M2 and M3 matching all requirements of OIML R111. ASTM weights are available in classes 1 - 6 matching requirements of ASTM E617. Nominal values range from 1mg to several tons, satisfying all industry and customer specific needs.Design and Construction
All knob and sheet weights are made of premium stainless steel to make them corrosion resistant. One-piece (monobloc) weights are specially designed for long term stability, and weights with an adjusting cavity provide best value for money. Electrolytic polishing ensures glossy surfaces for anti adhesion effects.
A global network of 11 Mass Laboratories in the US, Switzerland and other key markets guarantee fast and cost effective calibrations no matter where our customers are. All weights are manufactured with reference and traceability to the International Prototype Kilogram at the BIPM (International Bureau of Weights and Measures).
Traditional wooden boxes are still preferred in many mass labs while plastic boxes better serve the regulated and other industries. Impact resistant plastic boxes and high quality foam inserts do not show any dissolve effects or residues even after years of use. Labels are tested for high resistance against cleaning liquids.Accessories
Ergonomic tweezers and weight forks as well as clean-room approved gloves and cleaning cloths meet highest requirements of all industries and assure professional testing.
