Key Features AUD 500 Portable Ultrasonic Flaw Detector with hi-resolution color TFT LCD display.The background color and the wave color can be selectable according to the environment. LCD brightness can be manually set. Continue working over 8 hours with high performance lithium-ion battery module, easy to be dismantled and the battery module can be charged independently offline. It is light and portable, easy operation; superior reliability makes it long life. Functions ● Peak Hold: Automatically searching the peak wave inside the gate and hold it on the display. ● Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter. ● Continuous Record: Record the display continuously and save it to the memory inside the instrument. ● Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance. ● Defect Sizing: calculate the defect size ● Defect Evaluation: Evaluate the defect by echo envelope. ● DAC function: Distance Amplitude Correction ● AVG function: Distance Gain Size curve function ● Crack measure function: Measure and calculate the crack depth ● B-SCAN: Display the cross-section of the test block. Real-Time Clock Real time clock for tracking the time. Communicaion USB2.0 high-speed communication port Range 0~ 9999mm (at steel velocity); range selectable in fixed steps or continuously variable. Pulser ● Spike excitation with low, middle and high choices of the pulse energy. ● Pulse Repetition Rate: manually adjustable from 10 to 1000 Hz. ● Pulse width: Adjustable in a certain range to match different probes. ● Damping: 100Ω, 200Ω, 400Ω selectable to meet different resolution and sensitivity need. ● Probe work mode: Single element, dual element and through transmission; Technical Specifications ● Range: (0 ~ 9999) mm ● Bandwidth: (0.5 ~ 15) MHz ● Material Velocity: (1000 ~ 9999) m / s ● Dynamic Range: ≥ 32dB ● Vertical linear error: ≤ 3% ● Horizontal linear error: ≤ 0.1% ● Resolution:> 40dB (5P14) ● Sensitivity Leavings: 60dB (flat-bottomed deep hole 200mmФ2) ● Rejection: (0 to 80)% Linear ● Noise level: ≤ 10% ● Power supply: DC 9V; lithium batteries work for 4 to 8 hours or more ● Ambient temperature: (-20 ~ 50) ℃ ● Relative Humidity: (20 ~ 95)% RH Configuration
