Product Overview
Based on ultrasonic principle, digital ultrasonic flaw detector MFD500B with 320*240 TFT LCD, it can test, orient, evaluate and diagnose various flaws such as crack, lard, air hole in workpiece’s interior swiftly and accurately without any destruction. It can be used in Laboratory as well as in engineering filed. With range of 0-9999mm, it can meet the requirement for general defect inspection in manufacturing industry, metallurgical industry, metal processing industry, chemical industry and so on. Low power design with large capacity and high performance lithium battery module, it can be long standby for months. High quality with low price, it is the first choice for the practical economic model for ultrasonic testing equipment.

Features
Display
Hi-resolution (320×240 pixels) full digital TFT LCD with adjustable brightness, it is capable of providing high contrast viewing of the waveform from bright, direct sunlight to complete darkness.
The hi-resolution 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.
Range
Up to 6000 mm in steel; range selectable in fixed steps or continuously variable, suitable for use on large work pieces and in high-resolution measurements.
Pulse
Pulse Energy selectable among Low (300V), Medium (500V) and High (700V)
Pulse Repetition Frequency adjustable from 10 Hz to 1 KHz in 1 Hz increments
Damping selectable among 100Ω, 200Ω and 400Ω for optimum probe performance
Test Modes including Straight, Angle, Dual and Thru-transmission
Receiver
Sampling：10 digits AD Converter at the sampling speed of 160 MHz
Rectification：Positive Halfwave, Negative Halfwave, Fullwave and RF
Analog Bandwidth: 0.5MHz to 15MHz capability with selectable frequency ranges (automatically set by the instrument) to match probe for optimum performance.
Gain：0 dB to 110 dB adjustable in selectable steps 0.1 dB, 2 dB, 6 dB, and locked
Gates
Two fully independent gates offer a range of measurement options for signal height or distance using peak triggering.
The echo-to-echo mode allows accurate gate positioning for signals which are extremely close together.
Gate Start: Variable over entire displayed range
Gate Width: Variable from Gate Start to end of displayed range
Gate Height: Variable from 0 to 99% Full Screen Height
Alarms: Threshold positive/negative
Memory
Memory of 100 channel files to store calibration set-ups
Memory of 1000 wave files to store A-Scan patterns and instrument settings.
All the files can be stored, recalled and cleared.
Video Recorder
Screen scenes can be captured as movie files. About 2 minutes movie can be saved to the inside memory. They can be re-played using the instrument or the PC software delivered with the instrument.
Video Recorder is useful in many situations, convenient for those who want to analyze the probing activities later.
