Counterpoise and Hanger Calibration Weights are designed for precise suspended or ratio weighing in both laboratory and industrial settings. These cast iron weights, available in ASTM Class 7, are ideal for use in calibration setups where accurate counterbalancing is necessary.
Each weight is clearly marked with its nominal value and color-coded for quick recognition—gold-painted for metric units and silver-painted for avoirdupois (pound) units. For added convenience and accountability, serial numbers can be stamped on the weights upon request.
What sets these calibration weights apart is the rigorous two-step finish process they undergo. First, the weights are phosphatized—a cleaning and etching procedure that ensures optimal adhesion. They are then coated with chip-resistant paint, creating a rugged surface that stands up to wear and minimizes the risk of corrosion. This process guarantees reliable performance, even in demanding field environments.
