Choose your weight set according to your weighing needs and– with or without a calibration certificate. Sets range from 1 mg - 500 mg through 1 mg - up to 5 kg. Our stainless steel test weights are produced from the finest quality austenitic steel, which offers the highest resistance to corrosion during a weight’s lifetime.
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.
If two weights in the set have the same nominal value they are marked differently to enable secure identification.
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.
Weight sets consist of weights with different ranges: 1 mg - 500 mg through 1 mg - up to 5 kg which allows for flexible use according to your needs. Weight sets can be purchased either with or without a calibration certificate - check our portfolio of calibration weights.
Yes, the sets includes tweezers, a cleaning cloth and brush, to remove possible contamination from the weights.
The E1, E2 and F1 Classes weight sets (monobloc weights) are delivered in an aluminum box and the F1, F2 and M1 Classes weight sets come in a plastic box.
It depends on the weight set. We offer sets with 12 to 28 weights.
