This professional ultrasonic thickness gauge is an intelligent handheld thickness tester, which adopts ultrasonic measuring principle, andis controlled by micro processor, provides quick and precise measurement of thickness for most of industrial material. This ultrasonic thickness gauge is widely used in various precise measurement for different hardware / parts in industrial realm. One of its importantapplication is to monitor the level of thickness-decreasing during operation of various and pressure container. Features: Automatic calibration to assure high accuracy with 1.2225mm range. Automatic linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer. Make a quick adjustment for the sound velocity / thickness, and a quick recall to the stored data. 10 thickness measurement storage and recall function available, which facilitates the height work or working in wild area. 12 sound velocity for different materials which is also adjustable. Large LCD display with switchable backlight for easy readout. Low battery indication and auto power off. More than 10000 times long life keys. With a unique memory that retains all of its settings even when the power is off. Widely applied in manufacturing fields, metal processing, and commercial inspection.
