This handheld microprocessor-controlled ultrasonic thickness gauge is designed to measure the thickness of metallic and non-metallic materials such as aluminium, titanium, plastics, ceramics, glass, plastics including rubber and other ultrasonic wave conductors. It can also measure and determine the thickness of ALL hard materials with its sonic velocity without the removing or destroying anything (non-destructive measuring). Compact and easy to transport and use anywhere. Plus, it can shift velocity with 10m/s & 100/s increments and measure in both metric and imperial measurement units. Used in almost all kinds of industries as it can perform precise measurements on various types of raw materials, components, parts and assembled machinery. A must have device in monitoring all types of pipes and pressure vessels for loss of thickness due to corrosion or erosion, chemical equipment, boilers, oil storage tanks, and even in the industries of petroleum, shipbuilding, power station and machine manufacturing. It can measure any hard materials, including steel, cast iron, aluminum, red copper, brass, zinc, quartz glass, polyethylene, PVC, gray cast iron, nodular cast iron, acrylic, water glass and other materials.
