Cast Iron Calibration Weights – Slotted Interlocking and Hanger Weights are ideal for applications involving suspended weighing, such as testing crane scales or field calibration of heavy-duty industrial weighing devices. These slotted calibration weights are precision-crafted to meet ASTM and NIST specifications and are available in both metric and avoirdupois units.
Each weight is marked with its nominal value and color-coded for quick identification: gold paint designates metric weights and silver paint denotes pound (avoirdupois) weights. The optional stamping of serial numbers makes them suitable for traceable calibration and documentation protocols.
To ensure a long-lasting, corrosion-resistant finish, every weight undergoes a two-step phosphatizing and coating process. This involves thorough cleaning and mild etching for finish adhesion, followed by a tough, chip-resistant paint layer that conforms to NIST Handbook 105-1 standards.
Available Classes:
-
ASTM Class 6
-
ASTM Class 7
Applications:
-
Suspended weighing with hangers or interlocking weights
-
Field testing of industrial scales and Class III, IIIL, and IIII devices
-
Verifying scale accuracy for non-marked or unclassified devices
Ensure your industrial weighing systems maintain precision and compliance with these high-quality Slotted Cast Iron Calibration Weights. Built for durability, traceability, and easy handling, these weights are perfect for calibration professionals and field technicians.
