300g ASTM Class 4 Calibration Weights are satin-finished stainless steel and used with balances less sensitive than 0.01g for applications in which average accuracy is sufficient.
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 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 model number for NVLAP Certificate.
