Economical, quality weights

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

Weight tolerances 50% better than ANSI™/ASTM™ E617 Class 1

Economical Stainless Steel Class 7 Weight Set with No Certificate

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.

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.

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.

Economical and designed for educational use.
