500g Ultra Class Calibration Weights are highly-polished stainless steel, and designed to provide superior accuracy for analytical and sensitive balances and applications that demand it. They have weight tolerances 40-50% tighter than ASTM Class 1, and equal to or exceeding OIML Class E2.
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.
