Troemner OIML Individual Calibration Weights 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.
Applications Use OIML E1 as a primary reference to calibrate other mass standards and use for traceability between national mass standards and OIML E2 weights and lower. OIML E1 is appropriate for calibrating high-precision balances with a readability as low as 0.1 mg. Construction Weights 1 g and above are two-piece. Weights 500 mg and below are one-piece. Weights 50 kg to 1 kg are Troemner Alloy 8 or 316 Stainless Steel. Weights 500 g to 1 g are Troemner Alloy 8. Weights =500 mg are 303 Stainless Steel, 304 Stainless Steel or Aluminum. Design Features Weights 1g - 50kg have a tapered neck allowing easy handling, polished mirror-like finish allowing scratches or foreign matter to be seen, and bottom of weights are recessed to reduce wear. mg weights are flat with one end turned up for easy handling.
