Digital Portable MFD350B Ultrasonic Flaw Detector NDT Instruments Testing Equipment 0 ~ 6000mm
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, a spike pulser for applications requiring higher frequencies, and a tunable square wave 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.
Hi-resolution (320×240 pixels) multi-color TFT LCD with 4 user-selectable brightness control provides high contrast viewing of the waveform from bright, direct sunlight to complete darkness.
The hi-resolution multi-color TFT LCD display with fast 60 Hz update gives an analog look to the waveform providing detailed information that is critical in many applications including nuclear power plant inspections.
