• IP65 protection standard, durable, waterproof and dustproof, damping bracket at any angle;
• Single power 8 hours continuous work, 2 hours fast charging, can be charged independently, two pieces to achieve uninterrupted work.

Technical Data:

Note: The above indexes are measured at a probe frequency of 2.5MHz and a full-wave detection mode.

Main Function:

• Auto-calibration:One-button auto-calibration, very convenient operation，automatic testing of the probe’s “zero point”, “K value”, “front” and the material’s “speed of sound”;　
• Automatic display of defect echo position (depth d, level p, distance s, wave amplitude, equivalent dB, aperture ф value);　  
• Automatic gain, echo envelope, peak memory function improves the flaw detection efficiency;　
• φ value calculation: straight probe forging flaw detection, find the defects of the highest wave automatically converted aperture ф value, large flat bottom automatic calculation;　
• 500 independent flaw detection channels (expandable), free to enter and store any industry flaw detection standards, on-site flaw detection without carrying test blocks;　
• 1000 A-scan waveforms and data can be freely stored and played back (expandable);
• External U disk, internal storage can be exported at any time, you can also directly store an unlimited amount of flaw detection storage files.　
• Flaw detection video: dynamic video recording of the flaw detection process, through the expansion of the external U disk, it can realize unlimited time high-quality video recording;
• DAC and AVG are automatically generated and can be produced in segments, with unlimited sampling points, and can be corrected and compensated;
• 17 built-in probing standards can be adjusted out, you can freely input any industry standards;                                                       　
• Transmit pulse width and intensity adjustable;
• High-performance safe and environmentally friendly lithium battery power supply, standard can work continuously for more than 8 hours, optional battery capacity can be increased to 15 hours;　
• Real-time clock recording: real-time probing date and time tracking records, and storage;　
• Digital suppression, does not affect the gain and linearity;　
• Gain compensation: Db attenuation caused by surface roughness, thick workpiece long-distance flaw detection and other factors can be corrected;　
• Surface correction: used for curved surface workpiece flaw detection, it can display the circumferential position and depth of defects in real time;
• Angle and K-value input;
• Echo count analysis;　
• Echo coding: displaying 1~9 echoes in different colors, which is easy to judge the location of defects;
• Crack height measurement: automatically measure and calculate the crack height by using end-point diffraction wave;  　
• DAC sound and light alarm;　
• Freezing and unfreezing of the screen;　
• Two input methods of angle and K value;　
• Waveform filling;　
• Power status indication;　
• Capture marking;　
• In-gate waveform color marking;
• Waveform color marking in the gate;
• Widening in the gate.
