Features: 1.Suitable Type: Resolution of 0.1mm, measuring range of 0?10mm, the gauge can be used to measure the wall thickness of hollow tubes and round tubes. 2.Stable Performance: This thickness gauge is made of metal material, shockproof, waterproof and dustproof, and has high accuracy. 3.Outstanding Features: Excellent workmanship, fine scale, intuitive and precise, easy to carry, you can rest assured to use. 4.Lock Screw: With locking screw to fix the dial, so that the dial will not turn easily, so you can read accurately and clearly. 5.Unique Design: The thickness gauge is designed with a curved tip, which is lightweight and comfortable to hold in the hand, improving the experience and usability of the device. Specification: Item Type: Curved Tip Thickness Meter Material: Metal Purpose: To measure wall thickness of hollow pipe and round pipe Resolution: 0.1mm Measurement Range: 0-10mm/0-0.39in PackageList: 1 x CurvedTipThicknessMeter 1 x Storage Box Note: 1. When conducting the test to pay attention to the collective metal magnetism and surface roughness of the standard sheet should be similar to the test piece. 2. Measurement when the side head and the specimen surface to maintain vertical. 3. When measuring, pay attention to the critical thickness of the base metal, if it is greater than this thickness measurement is not affected by the thickness of the base metal.
