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 protective case.
All weights or sets are available with optional NIST Traceable or NVLAP Certificates. Traceable Certificates document traceability to NIST and compliance with ASTM or OIML specifications. Add “T” to the model number to specify a Traceable Certificate. NVLAP Weight Calibration Certificates provide certification to ISO, FDA, ANSI, or other requirements. Report format and contents comply with NVLAP requirements. Add "W" to the model number for the NVLAP Certificate.
