Features: 1.WIDE APPLICATION: Resolution 0.1mm, measuring range from 0?10mm, can be used to measure wall thickness, such as iron sheet, steel plate, wall pipe, etc. 2.ACCURATE AND STABLE: Thickness gauge possess high accuracy, shockproof, waterproof and dustproof, you can use with confidence 3.CLEAR SCALE: Round dial thickness gauge is made with solid workmanship, bring delicate scale, intuitive and accurate 4.SCREW FIXING: Come with locking screw, fix the dial, do not let the dial rotate, bring accurate reading 5.STURDY METAL: Using excellent metal material, shiny, sturdy and durable, possess good heat resistance, high mechanical strength, not easy to age Specification: Item Type: Thickness Gauge_x000D_ Material: Metal_x000D_ Application: Measure wall thickness, such as iron sheet, steel plate, wall pipe, etc._x000D_ Resolution: 0.1mm_x000D_ Measuring Range: Approx. 0 ~ 10mm / 0 ~ 0.39in PackageList: 1 x Thickness Gauge 1 x Storage Box Note: 1. During test, it should be noted that the metal magnetism and surface roughness of the standard piece should be similar to the test piece._x000D_ 2. Keep the side head perpendicular to the surface of the sample during measurement._x000D_ 3. Pay attention to the critical thickness of the base metal when measuring. If it is greater than this thickness, the measurement will not be affected by the thickness of the base metal.
