Mitech MT660 Multi Mode Ultrasonic Thickness Gauge

Mitech MT660 Multi Mode Ultrasonic Thickness Gauge

Product Overview

The Mitech MT660 is a next-generation ultrasonic thickness gauge, engineered for professionals who demand precision, durability, and ease of use in harsh industrial environments. Featuring an ultra-clear 320×240 color TFT LCD display, the MT660 delivers excellent readability in low light or under direct sunlight.

Its robust aluminum-magnesium alloy housing ensures protection against oil, dust, and impact, making it ideal for rugged field operations. With support for Pulse-Echo (P-E) and Echo-Echo (E-E) modes, it enables accurate thickness measurement even through coatings—eliminating the need to strip paint or insulation.

Bluetooth functionality, USB connectivity, and high-resolution measurement down to 0.001 mm put the MT660 in a class of its own for real-time monitoring, efficient data transfer, and reliable reporting.

Key Features

• Dual Measurement Modes:

  • Pulse-Echo (P-E): Measures total thickness including coatings.

  • Echo-Echo (E-E): Penetrates coatings to measure only base material.

• Ultra-High Resolution:
  Measures with precision up to 0.001 mm for detailed analysis.

• Smart Display:

  • Color TFT screen with adjustable backlight.

  • Visual alerts for out-of-range values for quick judgment.

• Data Management:

  • Internal memory stores 100 measurement groups (up to 100 readings each).

  • USB & Bluetooth for fast, wireless report generation and PC syncing.

• Robust Battery Life:
  Runs up to 30 hours on two AA batteries with auto power-saving functions.

• Advanced Sound Velocity Calibration:
  Features V-path correction and multi-point calibration for improved accuracy.

Applications

The MT660 is widely used for non-destructive testing (NDT) in various industries:

• Monitoring wall thickness of pipelines, tanks, and pressure vessels.

• Inspecting corroded or coated components without surface preparation.

• Measuring metal plates, plastic parts, ceramics, glass, and composites.

• Essential for sectors like oil & gas, chemicals, shipbuilding, aviation, metallurgy, and manufacturing.

Operating Principle

The device works by emitting an ultrasonic pulse through the test material and measuring the time it takes to reflect back. The formula used:

H = v × t / 2
Where:
H = Thickness
v = Material sound velocity
t = Transit time of pulse

Best Practices for Use

• Pipe & Tubing:
  Orient the transducer correctly (perpendicular or parallel) based on pipe diameter to ensure accurate results.

• Hot Surfaces:
  Use high-temperature transducers and calibrate at operating temperatures for reliable readings above 100°C.

• Laminated Materials:
  Always calibrate on sample pieces due to varied sound velocities. Be alert for internal air gaps which may reflect prematurely.

• Material Compatibility:
  Best suited for materials with good ultrasonic transmission—metals, plastics, ceramics, glass, and more.

• Couplants:
  Use glycerin, propylene glycol, or silicone oils for sound transmission. Special couplants may be needed for high-temp applications.

Maintenance & Warranty

• Do not attempt unauthorized disassembly.

• Keep away from moisture, corrosive environments, and heavy dust.

• Store in moderate temperatures.

• Use original packaging during transport.

• Warranty service available with a valid card.
