Calibration Weight Sets Adjusted to Meet or Exceed OIML Class E1, E2, F1, and F2 Tolerances
Troemner OIML Calibration Weight Sets offer the tightest tolerances, lowest uncertainties, and all surfaces are polished to a perfect finish to meet or exceed OIML R 111 tolerance and design restrictions. OIML Class E1, E2, F1, and F2 calibration weights are manufactured from high grade stainless steels including Troemner Alloy 8 which possesses closely controlled density, low magnetic susceptibility, and corrosion resistance.
OIML Calibration Weight Sets Features
OIML E1-E2 and F1-F2 offer high accuracy with tight tolerances and uncertainties of less than 1/4 of the tolerance. Weight surfaces meet or exceed OIML R 111and 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.
