20kg 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. These 20kg weights have recessed grip handles for easier handling.
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.
