MT600 Ultrasonic Thickness Gauge Mitech

MT600 Multi Mode Ultrasonic Thickness Gauge – Mitech

Product Overview

The Mitech MT600 Multi Mode Ultrasonic Thickness Gauge is a precision instrument designed for fast, reliable, and non-destructive measurement of material thickness. It supports both Pulse-Echo (P-E) and Echo-Echo (E-E) modes, allowing accurate thickness readings through coatings without needing to strip the surface. Equipped with a high-resolution 320×240 color TFT LCD, the device ensures excellent visibility in any lighting environment.

Its IP65-rated enclosure protects against dust, moisture, and oil, making it highly durable for industrial use. With Bluetooth and USB connectivity, the MT600 offers seamless data transfer and wireless report generation. It is widely used for corrosion monitoring, structural inspection, and quality control across various sectors such as oil and gas, shipbuilding, aerospace, chemical processing, and manufacturing.

Applications

• Corrosion monitoring of pipelines, pressure vessels, and tanks

• Structural inspection in aerospace, shipbuilding, and offshore industries

• Sheet metal thickness measurement in production and quality control

• Measurement of non-metallic materials such as plastics, ceramics, and composites

• Ideal for both field and laboratory applications

Working Principle

The MT600 operates using ultrasonic pulse technology. It sends a high-frequency sound wave into the material and measures the time taken for the echo to return. Thickness is calculated using:

H = (V × T) / 2

Where:
H = Measured thickness
V = Sound velocity in the material
T = Round-trip time of the ultrasonic pulse

Echo-Echo mode filters out coating thickness, measuring only the base material underneath.

Measurement Considerations

• For pipe thickness, align the probe perpendicular to the axis for pipes larger than 4 inches

• Use high-temp probes and calibrate accordingly when measuring hot surfaces above 100℃

• Calibrate for each batch when measuring laminated materials

• Use a proper couplant for ultrasonic transmission, such as water, glycerin, silicone oil, or high-temperature couplants

• Be aware of potential false readings due to second echo reflections; verify results for accuracy

Maintenance & Care

• Clean the unit with a soft, damp cloth—avoid solvents or abrasive materials

• Charge batteries fully before first use and after extended storage

• Replace batteries if operating time decreases significantly

• Store in a clean, dry place away from magnetic fields, corrosive agents, or dust

• Do not disassemble the device—contact an authorized service center for any repairs
