Product Features:
AR850 Ultrasonic Thickness Gauge is a compact, high-precision non-destructive testing (NDT) tool designed to accurately measure the thickness of metal, plastic, and other solid materials. By using ultrasonic pulse-echo technology, it enables users to measure thickness from one side of the material, making it especially valuable for inspecting pipes, tanks, structural parts, and components where only one side is accessible.
With a measurement range of 1.2–225mm, selectable 5MHz or 2.5MHz probe frequency, and 12-group sound velocity storage, the AR850 offers flexibility across different materials. Additional features such as auto zero calibration, backlight display, coupling indicator, and auto linear compensation make it ideal for engineers, maintenance personnel, and quality control professionals.
