MFD800C Ultrasonic Flaw Detector Mitech

MFD800C Ultrasonic Flaw Detector – Mitech

Product Overview

The Mitech MFD800C Ultrasonic Flaw Detector is a high-performance digital instrument designed for precise non-destructive testing (NDT) of internal flaws in materials such as metals and composites. With a wide measuring range up to 9999 mm (at steel velocity) and an advanced 640×480 TFT LCD display, it enables users to quickly identify and evaluate defects including cracks, air holes, and voids.

Built to IP65 protection standards, this device is waterproof, dustproof, and oil-resistant—ideal for rugged industrial environments. It features intelligent signal processing, large memory capacity, video recording, and intuitive controls, making it a powerful and user-friendly tool for quality assurance and structural integrity inspections in industries such as petrochemical, shipbuilding, aviation, and power generation.

Operating Principle

The MFD800C works using the ultrasonic pulse-echo method. An ultrasonic wave is emitted from a probe into the material. When the wave encounters a discontinuity, part of it reflects back to the probe. By measuring the time delay and signal amplitude of the returned echo, the device calculates the depth, location, and nature of the flaw.

Measurement Best Practices

• Always calibrate the device using reference standards before testing

• Apply a suitable couplant between the probe and test material for accurate signal transmission

• Select the proper probe type and frequency for the material and flaw size

• Use video recording for detailed defect analysis and documentation

• Clean the instrument after use and store it in a dust-free, non-corrosive environment
