Description
Product Introduction:
Digital ultrasonic flaw detectors enable rapid, convenient, nondestructive, and precise detection, localization, evaluation, and diagnosis of various internal defects in workpieces, including cracks, welds, porosity, blowholes, inclusions, and folds. They are widely used in industries such as power generation, petrochemicals, boiler and pressure vessel manufacturing, steel structures, defense, aerospace, rail transportation, automotive, and machinery. They are essential instruments in the nondestructive testing field.
Product Features
● High-precision quantification and positioning, meeting the requirements for both near-field and far-field flaw detection;
● The near-field blind zone is small, meeting the requirements for flaw detection in small-diameter, thin-walled pipes.
● Automatic Calibration: One‑button automatic calibration for extremely convenient operation, automatically measuring the probe’s “zero point,” “K‑value,” “front edge,” and the material’s “sound velocity.”
● Automatically displays defect echo parameters (depth d, horizontal position p, distance s, amplitude, equivalent dB, and aperture diameter φ).
● Freely switch among three measurement scales (depth d, horizontal p, and distance s);
● Four inspection modes: full-wave, RF, and AB scan;
● Automatic gain control, waveform freeze, and peak‑hold functions enhance flaw‑detection efficiency.
● Automatically records the flaw detection process and supports dynamic playback;
●φ‑value calculation: For straight‑probe flaw detection of forgings, the system automatically converts the aperture φ‑value based on the location of the defect’s highest echo.
● 1,000 independent flaw‑detection channels (expandable), allowing free entry and storage of inspection standards for any industry; on‑site inspections require no reference blocks.
● Freely store and replay 500 A-scan waveforms and associated data;
● DAC and AVG curves (depth compensation) are generated automatically, with no restrictions on sampling points, and can be adjusted and compensated.
● 14 built-in flaw detection standards can be recalled;
● Allows free entry of any industry standard;
● The pulse width and intensity of the transmitted signal are adjustable;
●B-scan functionality clearly displays the cross-sectional shape of defects;
●Stores data on a USB flash drive, replacing the traditional method of directly connecting to a PC for data export. Enables computer-based data management and supports exporting in BMP format, video files, and channel data.
● IP65‑rated ABS plastic housing, robust and durable, waterproof and dustproof, with excellent anti‑interference performance;
● Using USB‑based communication software, you can analyze data and generate printed reports, among other functions.
● 260,000‑color true‑color ultra‑bright display, ideal for both bright and low‑light working conditions;
● Powered by a high-performance, safe, and environmentally friendly lithium battery, it can operate continuously for 8–10 hours.
● Real-time clock recording: Tracks and stores the real-time date and time of flaw detection.
● Power-loss protection ensures data is not lost;
● Flaw detection parameters can be automatically tested or preset;
● Digital suppression, with no impact on gain or linearity;
● Gain Compensation: Enables correction of dB attenuation caused by factors such as surface roughness, curved surfaces, and long‑range flaw detection in thick workpieces.
● The software keyboard on the PC enables computer‑based control of the flaw detector’s main unit, thereby achieving the goal of performing flaw detection.
