Applications

The MT600 Ultrasonic Thickness Gauge is designed for non-destructive testing (NDT) and corrosion monitoring, making it an essential tool for:

• Pipeline and pressure vessel corrosion assessment
• Structural integrity inspection in aerospace and marine industries
• Sheet metal and machined part thickness verification
• Quality control in manufacturing and production environments
• Monitoring of composite materials, plastics, and ceramics

It is compatible with various transducer models, allowing measurement of coarse-grained materials and high-temperature applications.

Working Principle

The MT600 uses ultrasonic pulse technology to measure thickness by emitting a high-frequency sound wave through the material. The sound wave reflects off the back surface of the object and returns to the transducer. The device calculates the thickness using the formula:

H = (V × T) / 2

Where:

• H = Measured thickness
• V = Sound velocity in the material
• T = Round-trip transit time of the sound wave

The Echo-Echo mode eliminates coating thickness from the measurement, allowing accurate readings of the base material.

Measurement Considerations

• Pipe & Tubing Thickness Measurement:

  • For pipes larger than 4 inches in diameter, position the transducer perpendicular to the pipe axis.
  • For smaller pipes, take measurements in both perpendicular and parallel orientations and use the smaller value.

• Hot Surface Measurement:

  • Sound velocity decreases at high temperatures.
  • For surfaces above 100℃, calibrate the gauge using a sample at a similar temperature.
  • Use a high-temperature transducer and minimize probe contact time.

• Laminated Materials Measurement:

  • Sound velocity varies across laminated surfaces.
  • Calibrate using a sample from the same batch for accurate results.
  • Air gaps in laminates may cause premature reflections, affecting accuracy.

• Material Suitability:

  • Works well with metals, plastics, ceramics, and glass.
  • Less effective for cast materials, concrete, wood, fiberglass, and rubber.

• Couplant Usage:

  • A couplant is required to ensure proper sound transmission.
  • Recommended couplants: propylene glycol, glycerin (except for corrosion-prone metals), water, silicone fluids, and greases.
  • For high-temperature measurements, use a specialized high-temperature couplant.

• Pulse-Echo Mode Consideration:

  • The instrument may mistakenly use the second echo, leading to incorrect readings (double the actual thickness).
  • Users should carefully verify readings to ensure accuracy.

Maintenance & Care

• Cleaning:

  • Wipe the unit with a soft, damp cloth.
  • Avoid using methyl alcohol, solvents, or abrasive cleaners, as they may damage plastic components.

• Battery Maintenance:

  • Charge the batteries before first use and after prolonged storage (3+ months).
  • Replace batteries if frequent discharges reduce operating time.

• Storage & Handling:

  • Store in a dry, vibration-free environment, away from strong magnetic fields, corrosive substances, and excessive dust.
  • Do not disassemble the device. If technical issues occur, contact an authorized service center.

Warranty & Support

• Two-year warranty with lifetime maintenance support.
• In case of technical issues, contact the official distributor. Unauthorized disassembly will void the warranty.
