Portable Digital Hardness Tester 120mm×67mm×31mm Thickness Gauge MT660

MITECH MT660 Muti-mode Ultrasonic Thickness Gauge

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.

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.

Where:

H－Thickness of the test piece.

v－Sound Velocity in the material.

t－The measured round-trip transit time.

To make sure the probe working properly, it needs to use couplant to isolate the air between the probe surface and the measured workpiece surface. The liquid used for the coupling between the probe and workpiece is called as couplant.
