Counterpoise and Hanger Calibration Weight, ASTM Class 6

  • Counterpoise weights for ratio 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
  • Serial numbers may be stamped on weights (optional)

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.
