Ultrasonic Flaw Detector

HDU80 digital ultrasonic flaw detector can be quickly and easily, without damage, accurate to a variety of defects such as cracks within the workpiece, welding, air hole, inclusion, folding the detect

HDU80 Ultrasonic Flaw Detector Main features:
- High-precision quantitative, location, meet the more recent and more remote testing requirement;
- Near-field blind zone is small, to meet the small diameter, thin-walled tube testing requirements;
- Φ value: direct probe forging testing, identify the defective automatic conversion aperture ф highest wave value;
- Testing range (0-10000) mm, stepless adjustment;
- Automatic calibration: automatic test probe "zero", "K value", "forward" and material "velocity";
- Automatic display flaw echo location (depth d, level p, distance s, amplitude, equivalent dB, ф aperture value);
- Free switching of three gauge (depth d, the level of p, from s);
- Automatic recording dynamic testing process and can play back;
- Automatic gain, echo envelope peak memory improves testing efficiency;
- Power-down protection, storage, data is not lost;
- Testing parameters can be automatically tested or preset;
- Digital inhibition does not affect the gain and linearity;
- 10 independent testing channels are free to enter and store any industry testing standards, on-site testing without the need to bring test block;
- Free storage, playback 300 A scan waveform and data;
- DAC, AVG curve generated automatically and can create sub-sampling points without restriction, and may be modified and the compensation;
- Free to enter any industry standards;
- B scan clearly shows the shape of defects in longitudinal section;
- And computer communications, data management by computer, and can export the Excel format, A4 paper testing report;
- Real-time clock record: real-time testing date, time, track record, and store;
- Screen Saver: "Automatic Shutdown", "text", "free custom" and other free screensaver mode change;
- Gain compensation: on the surface roughness, surface, thick piece of remote testing and other factors can be modified Db attenuation;
- PC terminal communication software soft keyboard, computer control to achieve the goal of testing flaw host;
- Using PC-side software can be upgraded communications equipment function of the system;
- IP65 standard magnesium alloy casing, durable, waterproof and dustproof, anti-jamming capability is excellent;
- 26 million colors true color super-bright display, brightness adjustable, suitable for light, low light of the work environment;
- High safety and environmental protection lithium battery powered, can work for 7 hours.
- Other important auxiliary functions: 
● angle and K values of two input frequency analysis
● Echo Power status indication 
● screen freezing and thawing gate sound alarm ● ● clock display Sleep and screen savers
