Wintact WT130A Digital Ultrasonic Thickness Gauge, with USB charging, high precision This device transmits waves at a constant speed and can distinguish reflected waves from the back. Wide Applications: The ultrasonic thickness gauge is suitable for materials that conduct and reflect sound waves at a constant speed, such as metals, plastics, ceramics, glass, and others. It can also be widely used in manufacturing, metal processing, commodity inspection, and other materials that allow ultrasonic waves to pass through. It transmits waves at a constant speed and distinguishes waves reflected from behind the device. 2. It is widely used in manufacturing, metal processing, commodity inspection, and other materials that allow ultrasonic waves to pass through. 3. The ultrasonic thickness gauge is suitable for materials that transmit and reflect stable sound waves, such as metals, plastics, ceramics, glass, and others. 4. The smart portable ultrasonic thickness gauge is controlled by a microprocessor, enabling it to measure thickness quickly and accurately, and detect the properties of different materials without needing to measure them with ultrasonic waves. 5. The device can accurately measure parts of different materials, or be used in industrial production, as well as monitor pressure vessels in pipes and production equipment, and the degree of corrosion of different parts. 6. Measuring Range: 1.00 - 300.0 mm 7. Data Storage Capacity: 1500 8. 1.2V Nickel-Metal Hydride Rechargeable Battery (not included). Last offer 450 SAR Sale to the highest bidder, God willing
