Features
ASTM Reference Calibration Weight Sets
Troemner UltraClass offers high accuracy with tight tolerances and uncertainties of less than 1/4 of the tolerance. Weight surfaces meet or exceed ASTM and have a highly polished finish. Available in high grade stainless steels including Troemner Alloy 8 which possesses closely controlled density, extremely low magnetic properties, good stability, and resistance to corrosion. Available with certificate options traceable to NIST, including ISO/IEC 17025 accredited certification or traceable certification to aid in meeting SOP and regulatory requirements.
Applications
Use as a primary reference for calibrating other mass standards and use for traceability between national mass standards and ASTM Class 1 weights and lower. This class is appropriate for calibrating high-precision balances with readability as low as 0.01 mg.
Construction
1 g and above - two-piece 500 mg and below - one-piece
