Description
Product Introduction:
The JZT800PLUS digital ultrasonic flaw detector enables rapid, convenient, nondestructive, and precise detection, localization, evaluation, and diagnosis of various internal defects in workpieces, including cracks, welds, porosity, blowholes, inclusions, and folds. It is widely used in industries such as power generation, petrochemicals, boiler and pressure vessel manufacturing, steel structures, defense, aerospace, rail transportation, automotive, and machinery, making it an indispensable instrument in the nondestructive testing field.
Product Features:
★ Full‑screen guidance for probe calibration, curve generation, and other operations, with interactive dialog boxes—no need to consult the manual.
★ Fully equipped with tools including DAC, AVG, TCG, color‑coded B‑scan, AWS, and spheroidization ratio analysis.
★ Repetition rate: 10–3000 Hz, precisely adjustable; high-speed scanning ensures no defects are missed.
★ Ultra-high signal-to-noise ratio, with clear and stable waveforms; featuring a specialized anti-interference design that withstands harsh operating conditions.
★ 12-bit ADC, high-speed sampling, smooth waveforms, and exceptional detail; ultra-high sensitivity and resolution even for minute defects.
★ Automatic defect acceptance, intelligent evaluation, high-definition bright display, a three-dimensional and aesthetically pleasing interface, and a user-friendly operating style.
★ High-speed, real-time flaw detection recording; all inspection data can be stored via USB with unlimited expandability.
★ IP65 protection rating, alloy-and-silicone combined housing, robust and durable, waterproof and dustproof, with an adjustable damping bracket.
★ Automatic Calibration: One‑button automatic calibration for effortless operation, automatically testing 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);
★ Automatic gain control, echo envelope analysis, and peak‑memory functions enhance flaw‑detection efficiency.
★ φ‑value calculation: For straight‑probe flaw detection of forgings, the system automatically converts the defect’s peak amplitude into an equivalent aperture diameter φ‑value; for large flat-bottomed defects, the φ‑value is calculated automatically.
★ 500 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 1,000 A-scan waveforms and data (expandable);
★ Connect an external USB drive; internal storage can be exported at any time, and it also allows direct storage of an unlimited number of flaw‑detection data files.
★ Flaw Detection Video: A dynamic video of the flaw detection process, expandable via an external USB drive, enabling high‑quality recording with no time limit.
★ DAC, TCG, and AVG are automatically generated and can be created in segments; sampling points are unrestricted, and corrections and compensations can be applied.
★ B-scan: Real-time scanning and cross-sectional display, capable of visualizing the shape of defects in the workpiece, making the inspection results more intuitive.
★ 13 built-in flaw detection standards can be recalled, and any industry-specific standard can be entered freely;
★ The pulse width and intensity of the emitted signal are adjustable;
★ Powered by a high-performance, safe, and environmentally friendly lithium battery, with a standard runtime of up to 15 hours.
★ Real-time clock recording: Tracks and stores the real-time date and time of flaw detection.
