1 Introduction
The MFD350 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 10MHz RF bandwidth to permit testing of thin materials, narrowband
filters to improve signal to noise in high gain applications and a spike pulser to
optimize penetration on thick or highly attenuating materials.
The instrument can be widely used in locating and sizing hidden cracks, voids,
disbands, and similar discontinuities in welds, forgings, billets, axles, shafts,
tanks and pressure vessels, turbines, and structural components.
1.1 Features of the Instrument
The instrument extends the performance and range of applications that are
capable of being satisfied by a portable instrument. The quality, portability,
durability, and dependability that you have come to expect from the popular
Mitech MFD Series of instruments remain.
