美國(guó)特朗納Troemner高精度砝碼套裝Ultraclass

• UltraClass Tolerance = ASTM Class 0
• UltraClass weights, 1 g through 5 kg, are made from exclusive Troemner Alloy 8 stainless steel

這些重量是為了滿足zui苛刻的校準(zhǔn)需要，需要調(diào)整的能力。*性自動(dòng)測(cè)量意味著Troemner UltraClass重量是zui精確的兩件重量，重量公差等于或超過(guò)了類似的ANSI /ASTM E617類。

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.
