1mg–100g ASTM Class 4 Calibration Weight Set is satin-finished stainless steel and used with less sensitive balances for applications in which average accuracy is sufficient. Precision Weight Sets have weights supplied in 5-2-2-1 series as ASTM E617 specifies and a protective case.
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.
