Overview: MT660 multi-mode ultrasonic thickness gauge is the newest promoted upgraded product by Mitech. It pays more attention to user experience and functional innovation. Adopted with 320*240 colorful LCD display, it can show you clear measurement result under dim light and strong sunshine environment, improved the visual experience greatly. Sealed aluminum-magnesium alloy case delicate design, smaller volume, better quality are specially designed for defense against oil, dust in the bad sit environment. With intelligent warning function, it will promote automatically when beyond the setting range, it is convenient for reading. It can meet the efficient collecting material’s multiple points’ thickness accurate testing demand. It supports 0.001 high accuracy display and Bluetooth communication. With through coating mode and common mode, its unique performance of capable for testing thickness through the coating provides efficient solution for testing the workpiece of coated surface or corrosion materials. It can measure the workpiece directly without needing to get rid of the surface coating before measurement. It’s widely used for monitoring the production equipments’ various pipelines and pressure vessel corrosion reducing degree in the fields of petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and so on. It also can be used for making accurate measurement to various plates and machining parts. It is the necessary professional precision instrument for improving the production efficiency and qualification rate as well as saving cost. Function & application: Capable of performing measurements on a wide range of material, including metals, plastic, ceramics, composites, epoxies, glass and other ultrasonic wave well-conductive materials.Transducer models are available for special application, including for coarse grain material and high temperature applications. Instrument Features: Multi-mode: Pulse-Echo mode (P-E mode) and Echo-Echo mode (E-E mode). In Echo-Echo mode, it can test the wall thickness eliminating paint or coating thickness.Wide measuring range& 65306;Pulse-Echo mode: (0.65& 65374;600)mm (in Steel). Echo Echo mode: (3& 65374;100)mm .V-Path correction to compensate the nonlinearity of the probe.Color TFT display (320×240 TFT LCD) with adjustable backlight, allow the user to work at worksites with low visibility.Non-volatile memory can store 100 groups of test thickness. One hundred records max for each group.Two AA size alkaline batteries as the power source. Continuous operating period of no less than 100 hours (default brightness setting). Display Standby and Auto Power Off functions to save power.With internal Bluetooth module, it can print test report wirelessly. USB 2.0 communication port. Online transfer of the measured data to PC via USB. Working Principle: The digital ultrasonic thickness gauge determines the thickness of a part or structure by accurately measuring the time required for a short ultrasonic pulse generated by a transducer to travel through the thickness of the material, reflect from the back or inside surface, and be returned to the transducer. The measured two-way transit time is divided by two to account for the down-and-back travel path, and then multiplied by the velocity of sound in the material.
