50 m铟钢基线尺
Calibration baselines and comparator references need a tape that barely moves with temperature. This 50 m invar tape has an expansion coefficient of 0.5 × 10⁻⁶ /°C or less, Class I accuracy with certificate and 0–100 mm end scales. It is standardised at 100 N and stored on a 500 mm drum to avoid kinking.
