Calibration Weight, Ultra Class, 50g

50g Ultra Class Calibration Weights are highly-polished stainless steel, and designed to provide superior accuracy for analytical and sensitive balances and applications that demand it. They have weight tolerances 40-50% tighter than ASTM Class 1, and equal to or exceeding OIML Class E2.

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.
