Product OverviewThe Smart Sensor AS840 Ultrasonic Thickness Gauge is a professional-grade, non-destructive testing instrument engineered to measure the thickness of various materials with high precision. By utilizing ultrasonic wave technology, it can accurately determine the wall thickness of metals, glass, plastics, and other materials where access is restricted to one side. This makes it an essential tool for industrial maintenance, quality control, and pipeline inspection, particularly for detecting internal corrosion, erosion, or wear without damaging the integrity of the object.Key FeaturesNon-Destructive Measurement: Delivers accurate thickness readings without requiring disassembly or damaging the test object, making it ideal for finished products or in-service infrastructure.Broad Material Compatibility: Optimized for materials that effectively conduct ultrasonic waves, including steel, cast iron, aluminum, red copper, brass, zinc, quartz, and glass.Auto-Calibration: Features built-in auto-calibration capabilities to ensure measurement accuracy and high repeatability across different applications.High-Visibility Display: Equipped with a large, high-contrast backlit LCD screen, ensuring data is easy to read even in low-light environments.Data Management: Includes internal data storage and recall functions, facilitating efficient record-keeping and trend analysis during site inspections.Technical SpecificationsFeatureSpecificationBrandSmart SensorModelAS840Measurement Range1.0 – 300 mm (in Steel)Operating Frequency5 MHzAccuracy±(1%H + 0.1) mmWeightApprox. 220gDimensions~15.0 cm (L) x 7.0 cm (W) x 3.0 cm (H)Power Source3 x 1.5V AAA BatteriesSEO KeywordsSmart Sensor AS840, Ultrasonic Thickness Gauge, Non-Destructive Testing, Material Thickness Meter, Corrosion Inspector, Industrial Thickness Tester, AS840 Specs, Metal Wall Thickness Gauge, Precision Measuring Instrument, Ultrasonic Measuring Tool.
