Troemner Analytical Precision Metric Weights are available in Troemner UltraClass Platinum, UltraClass Gold, and UltraClass and ANSI/ASTM E617 Class 000, 00, 0, 1, 2, 3 and 4. Troemner Analytical Precision Avoirdupois Weights are available in ANSI/ASTM E617 Class 1, 2, 3, and 4. Analytical Precision Weights meet or exceed specifications as defined in the ANSI/ASTM E617 standard.
The weights are manufactured of the finest stainless steels available, including Troemner Alloy 8 Stainless Steel, which is available exclusively through Troemner. This unique material possesses closely controlled density (8.03 g/cm3), extremely low magnetic properties, good stability, and resistance to corrosion. Alloy 8 is the finest grade of stainless steel available and is similar to material originally specified in the manufacture of 1 kg state lab primary standards.
Weights are designed so the specifications on surface finish, markings, construction, material density, and magnetic properties become more restrictive as the weight tolerances decrease in order to enable the weight to maintain its tolerance over time. These weights are designed for your most demanding weighing applications.
