Designed specifically for adjustment of electronic balances and scales, our high-precision stainless steel weights provide easy handling and stacking. All weights are traceable to the SI through the National Institute of Standards and Technology (NIST). Weights are manufactured to one of the following specifications: ASTM E 617 or NIST Handbook 105-1. ASTM Class 0-4 stainless steel weights are available in sets, kits, and individual.
Rice Lake offers many configurations for their ASTM classification weight sets. Custom sets are available as build-to-order to meet your specific requirements. Each set consists of the weights, case, and appropriate lifting design.
Rice Lake offers individual stainless steel weights in Class F leaf or dish, cylindrical, and grip-handle styles to complement your NIST classification weight set.
Each weight set consists of the weights, case, and appropriate lifting device consisting of one or more lifter, tweezers, and white gloves.
Cast iron Class F grip-handle weights may be used to test most accuracy Class III scales, all scales of Class III L or IIII, and scales not marked with a Class designation. Class F is also acceptable for verifying scales that have a 0.1% accuracy and lower.
Cast iron Class F grip-handle weights larger than 5 kg (10 lb) are Legal for Trade.
