These 20 kg and 25 kg range calibration weight sets are manufactured to ASTM Class 4 tolerances, providing a robust and reliable standard for a variety of verification and testing procedures. The use of high-quality stainless steel with a polished finish ensures long-term stability and resistance to corrosion, which is critical for maintaining mass integrity over time. Each weight is clearly marked with its nominal value, facilitating quick and error-free use during calibration routines.
The sets are exceptionally versatile, suitable for calibrating Class I and II analytical and precision balances, performing verification checks on scales, and conducting tolerance testing. They serve as an ideal reference for creating ASTM Class 4, 5, and 6 working weights and are also perfectly suited for student laboratories and rough weighing operations where a known, traceable mass is required. For specialized needs, custom set configurations are available as build-to-order items to match specific capacity and increment requirements.
Ensure the ongoing accuracy of your laboratory and production floor scales with these certified weight sets. Contact our team today to request pricing, confirm availability, or speak with a calibration specialist for your laboratory or metrology requirements.
