General information about digital ultrasonic detector  ADUD-501-502-503-504
With high-precise positioning it meets requirements of close and distant detection.
Small blind near-field allows the detection of small diameter, thin-walled tube.
Automatic calibration:with one-button automatic calibration convenient operation, automatically testing the zero forwards of the probe and speed of sound of the materials.
Auto-display the location of flaw echo (depth d, distance s, amplitude, equivalent dB, aper true value).
Free switch to three kinds of standards (depth d, level p, distance s).
Auto-gain, return envelope, peak memory function improves detection efficiency.
Value calculation: forging straight probe testing, identifying the highest wave of defects, automatic conversing aperture value and calculating the large flat.
100 independent testing channels (expandable), you can freely enter and store any industrial testing standard, do field detection without test block.
• Freely store and playback 500A-scan wave forms and data
• DAC and AVG are automatically formed,without restriction of subsampling points and can be corrected and compensated.
• 13 built-in testing standards can be used
• You can freely enter and industrial standards
• The width and intensity of launch pulse are adjustable
• It can connect to the computer , realizing data management and exporting inspection reports of Excel format with A4 paper
• With the durable shell, oil-proof , water-proof and dust-proof
• 26 million colors ultra- bright display, adjustable brightness, suitable for both intense and low light working environment
• Battery with a good performance of safety and environment-friendly can work for 10 hours
• Time records: track and store records of testing date, time
• With power outage protection, stored data will not be lost
• Testing parameters can be automatically tested or preset
• With digital suppression no effects for the gain and linearity
• Gain compensation: correcting dB attenuation caused by surface roughness, surface curvature, distant- testing of thick piece and other factors
• Two input methods: angle
• Echo frequency analysis
• Power indicator
• Strobe audible and visual alarm
• DAC audible and visual alarm
• Screen lock and unlock
• Clock display
