Manufactured from stainless steel. The Troemner™ Stainless Steel Class 7 Weight Set is used for rough weighing operations in physical and chemical laboratories.

Made of vacuum melted steel for highest material purity

Primarily used to test commercial weighing devices by state and local weights and measures officials, device installers and service technicians. Class F weights may be used to test most accuracy Class III scales, all scales of Class IIIL or IIII, and scales not marked with a class designation.

Meets ASTM Class 4 adjustment tolerances and is ideal for applications requiring a degree of accuracy above general purpose weights

Economical, quality weights

High quality brass balance weights for use in calibration or as replacements for balance weight sets. Weight etched on top.

F1 OIML class weight set housed in an aluminum box includes accessories for handling and cleaning, and a calibration certificate.

For rough weighing operations in physical and chemical laboratories, such as force measuring apparatus.

Standard Line Weights. Specially used stainless steel, including the mg range, ensures anti corrosive surfaces with low magnetization and susceptibility values. Solid, one piece construction and mirror-polished surface grades give stable values.

Meet or exceed tolerances established for Class F in NIST Handbook 105-1
