Class F weights are precision calibrating units typically employed to test scales that are utilized in a variety of settings, from laboratory and pharmaceutical environments to commercial and industrial spaces. With tolerances as low as 0.0001%, Class F test weights from METTLER TOLEDO are calibrated to meet specific accuracy standards set by organizations such as the National Institute of Standards and Technology (NIST) and the International Organization of Legal Metrology (OIML).
Our stainless steel class F 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.
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.
To protect the integrity of weights and ensure a long lifespan, weights are supplied in a robust and easy-to-clean plastic container. Protective materials, including foam inserts, make them a durable solution.
