ASTM Individual Reference Calibration Weights
: Troemner
UltraClass offers high accuracy with tight tolerances and uncertainties of less than ¼ 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.
