This smart sensor AS840 gauge meter portable tool uses ultrasonic measurement technology. It is controlled by a microprocessor to provide quick and precise thickness measurements for most industrial materials. This instrument is often used in the industrial world for accurate measurement of various hardware/parts. One of its most important applications is to control the degree of thinning during the operation of different pressure vessels. This unit is suitable for measuring good ultrasonic conductive elements like plastic, metal, ceramic, and glass. The smart sensor features a 1000~9999m/s sound velocity range, 1.2~225mm measuring range, ±(1%H+0.1)mm accuracy, 0.1mm resolution, 5MHz frequency, 4-digital LCD display, 0°C~40°C operation temperature.
