Setting Disc / OD Setting Master is a precision reference master used for setting measuring instruments such as horizontal comparators and length measuring machines for accurate OD (Outside Diameter) checking.

These setting masters are also used as High / Low Masters for Air Calipers or Air Ring Gauges, providing an accurate dimensional reference for calibration, inspection, and quality control applications.

• Made from OHNS Steel, Chrome, Tungsten Carbide, and D2 material with Std/Customized XXX/XX/X/Y/Z/ZZ Classes/Tolerance.
• Masters are lapped to size and hand polished to provide superior accuracy, roundness, cylindricity, and wearability.
• Manufacturing Range: Dia. 0.5 - 300 mm.
• Subzero treated at -80°C for Dimensional Stability.
• Calibrated at 20°C under Standards Room conditions.
• Gauges are delivered in plastic case, providing anti-corrosion effect and impact resistance with Calibration Certificate (NABL/NPL Accredited).
