1g–100g Ultra Class Calibration Weight Sets are supplied in 5-2-2-1 series in accordance with ASTM E617. They are made of highly polished stainless steel, with weight tolerances 40 to 50% tighter than ASTM Class 1. Also available with NIST or NVLAP certification. The set includes a protective foam-lined plastic case and glove.
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.
