MT660 High Accuracy Digital Through Coating Ultrasonic Thickness Gauge Meter with Multi-Mode

Product Overview

The model MT660 is a multi-mode ultrasonic thickness gauge. Based on the same operating principles as SONAR, the instrument is capable of measuring the thickness of various materials with accuracy as high as 0.1/0.01 /0.001millimeters.

The multi-mode feature of the gauge allows the user to toggle between pulse-echo mode (flaw and pit detection), and echo-echo mode (eliminate paint or coating thickness).

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：Pulse-Echo mode: (0.65～600)mm (in Steel). Echo

Echo mode: (3～100)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. The result is expressed in the well-known relationship: H=v×t/2
