Product Overview:

The model MT150/MT160 is a digital 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 millimeters. It is suitable for a variety of metallic and non-metallic materials.

Product Specifications:

Display： 4.5 digits LCD with EL backlight.

Measuring Range： (0.65～300)mm (in Steel).

Sound Velocity Range: (1000~9999) m/s.

Resolution： MT150: 0.1mm; MT160: 0.1mm/0.01mm

Accuracy： ±（0.5%Thickness+0.04） mm, depends on materials and conditions

Units: Metric/Imperial unit selectable.

Four measurements readings per second for single point measurement, and ten per second for Scan Mode.

Memory for up to 20 files (up to 99 values for each file) of stored values.

Power Source ： Two “AA” size, 1.5 Volt alkaline batteries. 100 hours typical operating time (EL backlight off).

Communication： RS232 serial port for MT160. No communication port for MT150.

Outline dimensions： 150mm×74mm×32 mm.

Weight： 245g

Main Functions:

*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.

*Probe-Zero function, Sound-Velocity-Calibration function. Two-Point Calibration function.

*Two work modes: Single point mode and Scan mode.

*Coupling status indicator showing the coupling status.

*Battery information indicates the rest capacity of the battery.

*Auto sleep and auto power off function to conserve battery life.

*Optional software to process the memory data on the PC for MT160.

*Optional thermal mini-printer to print the measured data via RS232 port for MT160.

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.

Note： We do not ship the liquid ultrasonic couplant.
