20kg ASTM Class 1 Calibration Weights are highly polished stainless steel and recommended for analytical balances requiring first-order accuracy. ASTM Class 1 Calibration Weights range from 10g–4,000g.
All individual weights or weight sets can be ordered with an optional NIST or ISO certification.
Add “T” to the model number to request a Traceable NIST Certificate, which complies with ASTM E617 specifications.
Add “W” to the model number to request the ISO/IEC 17025 Certificate. This provides internationally recognized proof of calibration competence and supports compliance with regulatory requirements such as FDA, ANSI, and ISO.
