OBA-415 20kg ASTM Class 4 Calibration Masses are satin-finished stainless steel and used with balances less sensitive than 0.01g for applications in which average accuracy is sufficient. OBA-415 20kg masses have recessed grip handles for easier handling.
All masses 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.
