Ultra Class Calibration Weight Set,1mg–100g

Ultra Class Calibration Weight Sets, 1mg–100g come in a 5-2-2-1 series as indicated in ASTM E617. These weights are made of highly-polished stainless steel, and have weight tolerances 40 to 50% tighter than ASTM Class 1. Sets are also available with NIST or NVLAP certification. These come with a glove and foam-lined protective plastic case and glove.

Calibration weights check span and linearity and calibrate electronic balances. An increasing number of laboratories are doing their own internal calibration of balances to remain compliant with industry standards, and to pass external audits. A common calibration method is Span Calibration which uses one-point calibration with a single mass that approximately equals the balance’s capacity.

• Tighter weight tolerances
