CJE-220 AC Electromagnetic Yoke Flaw Detector

Lightweight AC yoke flaw detector with high sensitivity, low power, ideal for B2B industrial NDT inspection tasks.

  • High Detection Sensitivity
    Uses low-frequency rectangular pulse current for enhanced flaw detection.

  • Compact & Lightweight Design
    Easy to carry and operate, ideal for field and mobile inspections.

  • Low Power Consumption
    Efficient energy use extends operation time and improves reliability.

  • Direct AC Power Supply
    Simple setup with stable power input for consistent performance.

  • Optimized Component Matching
    Seamless coordination between probe, battery, and lighting for better usability.

This series of flaw detectors is powered directly from an AC power supply. The CJE-220 series features high sensitivity, low power consumption, lightweight design, and easy portability.

The instrument adopts a low-frequency rectangular pulse power source, ensuring optimal matching between the battery, probe, and illumination light. Additionally, the use of low-frequency rectangular pulse current magnetization significantly enhances flaw detection sensitivity.
