The MFD500B is an advanced digital ultrasonic flaw detector featuring a high-resolution multi-color TFT LCD with new features to meet challenging inspection requirements. It combines the powerful flaw detection and measurement capabilities. In addition, it has extensive data storage and capable to transfer detailed inspection data to PC via its high-speed USB port. The instrument incorporates many advanced signal processing features such as 15MHz RF bandwidth that permits 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.
The background color and the wave color can be selectable according to the environment. The LCD brightness can be manually set and the battery module can be charged independently offline. 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. The quality, portability, durability, and dependability that you have come to expect from the popular Mitech MFD Series of instruments remain.
