Digital ultrasonic flaw detector Leeb 510/520/521/522

Function & Feature:

• 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 onebuttonautomatic calibration, convenient operation, automatically testing the "zero", "K value", "forward" of the probe.
• Auto-display the location of flaw echo (depth d, level p, distance s, amplitude, equivalent dB, ф aperture value).
• Free switch to three kinds of standards (depth d, level p, distance s).
• Auto-gain, return envelope, peak memory function improves detection efficiency.
  
• φ value calculation: forging straight probe testing, identifying the highest wave of defects, automatic conversing ф aperture value.
• 100 independent testing channels (expandable), you can freely enter and store any industrial testing standard.
• Freely store and playback 500 A-scan wave forms and data.
• DAC and AVG are automatically formed, without restriction of sub-sampling points, and can be corrected and compensated.
• 13 built-in testing standards can be used.
• You can freely enter any 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, distanttesting of thick piece and other factors.
• Two input methods: Angle and K values.
• Echo frequency analysis.
• Power indicator.
• Strobe Audible and visual alarm.
• DAC Audible and visual alarm.
• Screen lock and unlock.
• Clock display.
