Ultrasonic Flaw Detector Mitech MFD350B

Ultrasonic Flaw Detector Mitech MFD350B

Product Overview

The Ultrasonic Flaw Detector Mitech MFD350B is a compact, high-performance non-destructive testing (NDT) device designed to detect, evaluate, and diagnose internal defects such as cracks, voids, and inclusions in a wide range of materials. Utilizing advanced ultrasonic pulse technology, the MFD350B delivers accurate real-time flaw analysis without causing damage to the tested object.

Its 320×240 TFT LCD display ensures clear visibility of results even in industrial environments. With a wide measuring range up to 6000 mm at steel velocity, the MFD350B is ideal for weld inspection, component integrity evaluation, and quality assurance across industries like manufacturing, metal processing, aerospace, and infrastructure.

Applications

• Weld inspection in pipelines, pressure vessels, and structural frames

• Quality control in manufacturing and metal processing industries

• Defect evaluation in shafts, axles, and mechanical parts

• Flaw detection in storage tanks, turbines, and heavy equipment

• Infrastructure inspection in aerospace, railway, oil and gas, and construction

How It Works

The device emits an ultrasonic pulse that travels through the material. If the wave encounters a defect, it is reflected back to the transducer. The time it takes for the echo to return is used to determine the depth, size, and location of the flaw. The results are displayed in real-time on the screen, providing immediate feedback to the operator.

Operating Method

1. Connect the probe to the instrument

2. Power on the device and select the desired detection channel

3. Calibrate the probe:

   • Straight probe: set P-Delay

   • Angle probe: set P-Delay, X-Value, Angle

4. Create an AVG/DAC curve based on probe type
