Advantages

Protection and Longevity

To protect the integrity of the weights and ensure a long lifetime, all weight sets are supplied in a robust, easy-to-clean aluminum (OIML E1-F1) or plastic (ASTM 1-4 and OIML F1-M1) case. Protective materials, including foam inserts, make them a durable solution.

Identification of Weights with Identical Nominal Value

If two weights in the set have the same nominal value they are marked differently to enable secure identification.

Weights with Calibration Certificate: Solid Compliance with Full Traceability

Test weights with calibration certificates offer the best results when documentation and traceability in balance routine testing are key. Monitoring the performance of your weighing equipment is usually required by standards like GMP or those of an internal quality-assurance department. For example, if you work according to ISO 9001, documented metrological traceability is required. Calibration certificates from a METTLER TOLEDO calibration laboratory are produced in accordance with ISO/IEC 17025 to fulfill these 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.
