Standard Features
- Slotted weights and hangers for suspended weighing
- Nominal value marked on weight
- Weight capacities of 10 kg/20 lb and up meet NIST Handbook 105-1 and Handbook 44 specifications
- Metric weights designated by gold paint
- Avoirdupois weights (pound) designated by silver paint

Our cast iron weights undergo a special phosphatizing process in which the metal is thoroughly cleaned and mildly etched to allow exceptional finish adhesion. The weights are then coated with a layer of chip-resistant paint which conforms to NIST Handbook 105-1 standards. This two-step process ensures a long-lasting finish that greatly reduces the possibility of corrosion.
Classes Available:
- ASTM Class 6 and 7
Applications:
- Field standards for testing industrial devices Class III, Class IIlL or IIII
- Testing for non-marked scales without Class designation
- Verifying scales are within specified accuracy and tolerances
