Mitech MT190 Ultrasonic Thickness Gauge

Mitech MT190 Multi-Mode Ultrasonic Thickness Gauge

Product Overview

Mitech MT190 Ultrasonic Thickness Gauge is a precision-engineered, multi-mode ultrasonic thickness gauge designed for non-destructive measurement of material thickness, even through coatings or corroded surfaces. Built to support both Pulse-Echo (P-E) and Echo-Echo (E-E) measurement modes, this versatile tool allows technicians to accurately evaluate wall thickness from one side of the material, making it ideal for inaccessible or closed structures.

With a durable, compact design and high-resolution output, the MT190 is used extensively in industries such as petrochemical, aerospace, metallurgy, and manufacturing for routine inspection, corrosion monitoring, and quality control tasks.

Key Features

• Dual-mode operation with Pulse-Echo (P-E) and Echo-Echo (E-E) for bare and coated surfaces

• Compatible with a wide range of materials including metals, plastics, glass, ceramics, and composites

• Supports special transducers for coarse grain and high-temperature materials

• Fast measurement speeds up to 16 readings per second in scan mode

• Intelligent calibration with probe-zero, sound velocity, and two-point options

Best Practices for Measurement

• For pipe measurements, ensure the transducer is aligned based on the pipe’s diameter

• On high-temperature surfaces, use suitable high-temp probes and calibrate at working temperature

• When measuring laminates, calibrate for each sample to accommodate variable sound velocities

• Always apply the correct couplant to promote effective ultrasonic wave transmission

• Watch for signal anomalies or echo duplication when dealing with curved or corroded surfaces
