If your scale isn't calibrated, it can cost you a fortune! Our 100g calibration weights routinely test the performance of your balance for long-term accuracy. Each 100g calibration weight is made of premium stainless steel boasting long life and proven corrosion-resistance. Along with an electropolish finish, for a shiny, anti-adhesive surface. Make sure your scale remains fit for purpose and can handle anything you throw at it.
Our stainless steel test weights in the design of knob weights with and without adjusting cavities as well as wire or sheet weights in the milligram range are produced from the finest quality austenitic steel which offers the highest resistance to corrosion over a weight’s lifetime. Our 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. ASTM Classes 1-4, 1mg - 20kg and OIML Classes E1, E2, F1, F2 & M1, 1mg – 20kg (50kg)
Monitoring the performance of your weighing equipment is typically required by standards like GMP or the internal quality assurance department. For example, if you work according to ISO 9001, documented metrological traceability is required and test weights with a certificate are necessary. Calibration certificates from a METTLER TOLEDO calibration laboratory are produced in accordance with ISO/IEC 17025 to fulfill metrological traceability requirements. However, using test weights without a calibration certificate may be acceptable in certain cases. Choose your test weights according to your specific requirements – with or without a calibration certificate.
To protect the integrity of weights and ensure a long lifetime, weights are supplied in a robust and easy-to-clean plastic container. Protective materials, including foam inserts, make them a durable solution.
