Individual Calibration Weights with Certificate
Applications
Use Class 1 as a primary reference to calibrate other mass standards and use for traceability between national mass standards and ASTM Class 2 weights and lower. Class 1 is appropriate for calibrating high-precision balances with readability as low as 0.1mg.
Design Features
Knob style weights 50kg–1 g are cylindrical with knob. Cal-Pak 5kg weight is a grip handle weight. Cylindrical style weights 1kg–5k have groove. Cylindrical grip style weights 4kg–30kg have recessed grip. Cylindrical weights 10g–600g are straight cylinder.
Individual Calibration Weights Adjusted to Meet or Exceed ASTM Class 1-4 Tolerances, with Certificate
- ASTM Class 1-4 offer 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.
