Selecting Calibration Weights

Rice Lake Weighing Systems manufactures a wide selection of quality calibration weights for various applications. Use the resources below to help select the right weight for the right application.

Calibration Weights and Configurations

Rice Lake offers test weights as individual weights, weight kits or weight sets.

Weight Kits

Weight kits include the test weight, a case or vial for the test weight, and a proper lifting device to handle the test weight. All cylindrical ASTM kits (excluding grip-handle weights) include their own protective case and glove set for safe handling.

Weight Sets

Weight sets include the test weights, a case for the test weights, and a proper lifting device to handle the test weights.
Sets may be ordered in a 5-2-2-1 or a 5-3-2-1 configuration.
For example, a set might include

  • (1) 50 g weight, (2) 20 g weights, and (1) 10 g weight, or
  • (1) 50 g weight, (1) 30 g weight, (1) 20 g weight, and (1) 10 g weight.

OIML and ASTM test weight sets larger than 500 grams, or one pound, include a hardwood case with velvet-lined pockets. Test weight sets with the largest weight of 500 grams include a precision-machined polyvinyl, crush-resistant case.

Serial numbers are not stamped on polished or milligram weights. A test weight should be more accurate than the precision of the weighing device, and it is recommended that a test weight has an accuracy of one-third the weighing device readability.
