Ultrasonic Thickness Gauge Industrial-888 FUNCTION AND SPECIFICATION: Measurement range: 0.039-19.685in / 1-500mm (45#steel) Resolution: 0.03 - 10in : 0.001in // 10-13.77in : 0.01in (0.8-100mm：0.01mm / 100-225mm：0.1mm); Sound Velocity Range: 1000~9999m/s; (five preset and one custom); Measurement period: 4 times/second; Measurement modes: Mode-IE (Echo-Echo mode) / PE-mode / VERI (Test) mode; Display: 2.0'' FSTN,128*64 dot matrix, LED backlight; Data Storage: 500 groups of measurement results, including measurement time and sound velocity information; Display Content: Thickness value, coupling state, electric quantity state, calibration state, sound velocity, time, etc; Measuring through the coating: IE-mode can pass through 20 mils (500μm) coating; Units of measurement: Metric / imperial (mm/in); Auto Power off: Automatic shutdown without action for 2 minutes (settable), with switch button; Size: 6,1*2,68*1,06in or (155*68*27mm); Power supply: 2*1.5V AA battery; We offer you the best ultrasonic thickness gauge Industrial-888 Mode-IE (Echo-Echo mode) which allows you to measure the thickness of the base through the coating (eg paint). That is, it is possible to measure the thickness of a metal product through a coating without first removing the paint or other protective coating. In this measurement mode, coating thickness can reach up to 20 mils, but the measurement range at 20 mils coating thickness is up to 3 inches. (The higher the thickness of the coating, the smaller the measurement range of the base) PE-mode is the standard mode for measuring uncoated bases and also for measuring Cast Iron The measurement range of the Ultrasonic Thickness Gauge Industrial-888 is 0.039-19.685in (1-500mm). VERI (Test) mode allows you to check if precious metals are counterfeited and determine their purity. The thickness gauge can be used to identify gold bars, silver bars, gold coins, silver coins and other precious metals. Ultrasonic thickness gauge Industrial-888 from VVV-Group uses the principle of ultrasonic measurement of the thickness of various materials. Thickness gauge Industrial-888 has a significantly higher accuracy compared to other ultrasonic thickness gauges and can be used in industry to produce high-precision measurements of the thickness of the base of various materials, such as Steel, Other metals and even Cast Iron, PVC, Glass, Ceramics and many others. It is widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields. This model is equipped with an ECHO mode and can be used to measure metal thickness through paint or other coatings. (IE) Echo to echo interface, which is suitable for measuring the thickness of various materials in which ultrasound can propagate at a constant speed. (You must first set the appropriate sound speed in the thickness gauge menu for the material). Important Note!!! This is NOT a coating thickness gauge, it is used to measure the thickness of the substrate.The binder is necessary for the measurement and must be evenly applied to the measured points on the surface of the object under test.Thickness can be measured by lightly pressing the feeler gauge against the surface of the object to which the couplant has been applied. Can be used in industry to produce high-precision measurements of the thickness of the base of various materials, such as Steel, Other metals and even Cast Iron, PVC, Glass, Ceramics and many others. IE-Mode (Echo-Echo) for measuring the thickness of the base through the coating PE-Mode (pulse mode) for standard measurement and also for measuring Cast Iron VERI (Test) Mode allows you to check if precious metals are counterfeited and determine their purity
