Rice Lake Counterpoise and Hanger Calibration Weights provide a precision-calibrated solution designed for ratio weighing applications and general field calibration tasks. These ASTM Class 7 weights are especially suited for non-legal-for-trade and industrial environments requiring robust, consistent, and well-marked calibration tools.
Each weight is color-coded—gold for metric and silver for avoirdupois (pound)—and features clearly marked nominal values to prevent confusion during calibration. With optional serial number stamping, users can ensure proper traceability for compliance and quality assurance.
Built from rugged cast iron, the weights undergo a special two-step phosphatizing and paint process. This treatment creates a corrosion-resistant, chip-resistant surface that prolongs the life of the weight, even in demanding field environments.
Whether you're testing Class III, IIIL, or IIII industrial devices or calibrating non-marked scales without class designations, Rice Lake’s counterpoise weights deliver reliable performance and durability.
