30 kg - 5 kg Single Calibration Weight, ASTM Class 2

Key Highlights

• Designed to meet ASTM Class 2 tolerances for precise scale calibration.

• Supplied as a single, solid weight for reliable high-mass reference.

• Features a nominal value permanently marked on the weight for clear identification.

• Includes a sealing cavity for adjusting material in weights of 100 g or larger.

• Conforms to a density of 7.84 g/cm³ for accurate use in standard air density.

This single calibration weight serves as a fundamental standard for verifying the performance of industrial and laboratory scales with capacities at 30 kg and 5 kg points. Its construction adheres to ASTM Class 2 specifications, providing the necessary tolerance levels for critical calibration, routine testing, and quality control procedures where high-mass accuracy is non-negotiable.

The weight incorporates a sealed adjustment cavity, a standard feature on masses of 100 grams and larger. This cavity allows for fine-tuning the weight to its exact nominal mass, ensuring it meets the stringent Class 2 tolerance requirements before being sealed to protect the adjustment material from environmental contamination. The consistent material density of 7.84 g/cm³ further enhances its reliability, minimizing buoyancy corrections during precise calibration work in controlled environments.
