Color TFT Display Coating Thickness Tester With Adjustable Backlight MT600

Product 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.

Measuring Principle

The 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.
