Troemner™ Individual Analytical Precision Weights, UltraClass with NVLAP Certificate

Description

Highly polished kilogram and gram weights

Made of Troemner Alloy 8, a specially developed austenitic stainless steel that possesses closely controlled density, extremely low magnetic permeability, good stability, and resistance to corrosion and handling damage.

• Exclusive material has a density of 8.0 at 25°C (controlled to ±0.1%), is essentially nonmagnetic in the annealed condition, and will not transform to magnetic under any combination of temperature and cold work down to -195.5°C (-320°F)
• Fractional weights 500mg to 50mg are made of stainless steel (30mg weights are aluminum); fractional weights 3mg and below are aluminum
• The UltraClass weight tolerance is equal to ANSI/ASTM E617 Class 0 and exceeds OIML R 111 Class E2
• This class is used as a reference standard for calibrating other reference standards and weights and is appropriate for calibrating high-precision analytical balances with a readability as low as 0.01mg
• Weights are supplied with a NIST/NVLAP Weight Calibration Certificate
• Weights supplied in a rugged, precision-fit, high quality polycarbonate case
