HIGH-PRECISION MATERIAL THICKNESS MEASUREMENT — ultrasonic pulse-echo technology measures true material thickness (not coating) with resolution up to 0.01in / 0.01mm, ideal for steel, aluminum, plastic, glass and other homogeneous materials. EASY FOR ANYONE TO USE — simple menu and clear interface allow fast setup and measurement in minutes; suitable for quick field checks as well as high-accuracy industrial thickness inspections. EASY FOR ANYONE TO USE — simple menu and clear interface allow fast setup and measurement in minutes; suitable for quick field checks as well as high-accuracy industrial thickness inspections. WIDE MEASUREMENT RANGE — thickness range from 1–400 mm (0.04–15.75 in) covers thin sheets and thick structural components, suitable for pipelines, tanks, plates and solid materials. ADJUSTABLE SOUND VELOCITY — manual sound speed setting from 1000–9999 m/s enables accurate calibration for different materials and ensures reliable results in professional environments. DATA STORAGE & STATISTICS MODE — stores up to 100 measurement groups and displays average, minimum and maximum values, supporting repeatable measurements and quality control documentation. SINGLE & CONTINUOUS MEASUREMENT MODES — supports spot checks and continuous scanning, ideal for industrial inspection, maintenance, research and production quality control. OVERVIEW Industrial-886 Ultrasonic Thickness Gauge by VVV-Group is a professional digital instrument designed for non-destructive measurement of material thickness. It measures the true thickness of the substrate, not paint or coating, making it ideal for industrial inspection, maintenance and quality control. This ultrasonic thickness tester uses pulse-echo technology to accurately measure metals and homogeneous non-metal materials such as plastic, glass, ceramics and rock. It is widely used in petroleum, chemical, metallurgical, shipbuilding, aviation and manufacturing industries. TECHNICAL SPECIFICATIONS Measurement principle: Ultrasonic pulse-echo Measurement range (steel): 1–400 mm (0.04–15.75 in) Resolution: 0.01 mm / 0.01 in Accuracy: ±0.04 mm (thickness <10 mm) Testing frequency: 5 MHz Sound velocity range: 1000–9999 m/s Measurement modes: Single measurement / Continuous measurement Data storage: Up to 100 data groups Display: Digital LCD Couplant required: Yes KEY FEATURES Measures base material thickness, not coating or paint Suitable for metals and non-metal homogeneous materials Adjustable sound velocity for accurate material calibration Built-in data memory with measurement statistics Displays average, minimum and maximum values Industrial-grade accuracy for professional applications HOW TO USE Select the material or manually set the sound velocity Apply ultrasonic couplant to the measurement surface Place the probe firmly on the surface Read the thickness value on the display Use continuous mode for scanning if required COMPARISON Unlike coating thickness gauges, Industrial-886 measures the true thickness of the material itself. Compared to basic ultrasonic testers, it offers adjustable sound velocity, data storage and statistical analysis, making it suitable for professional industrial use.
