Mitech MFD620C
The MFD620C is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its high-speed USB port.
The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.
Its waterproof, oil proof, dustproof function can achieve IP65 protection level. It is the necessary professional precision instrument for defect detection, quality control, on-line safety monitoring and life evaluation in fields of oil, chemical, metallurgy, shipbuilding, aviation, railways and so on.
