HEF-24ET Multi-Frequency Eddy Current Flaw Detector for Boiler Tubes & Heat Exchangers

The HEF-24ET is an intelligent multi-frequency eddy current detector representing the latest generation of nondestructive testing equipment. Incorporating advanced digital electronics, multi-frequency eddy current technology, and microprocessor technology, it enables real-time detection of inner and outer wall cracks in both ferromagnetic and non-ferromagnetic metal pipes.

This comprehensive eddy current testing system combines regular frequency and multi-channel capabilities into a high-performance, multi-purpose intelligent system. With multiple independent test channels, it captures both absolute and differential eddy current signals across a broad frequency range (50Hz to 10MHz).

• Multiple independent testing channels (up to four frequency mixing units)
• Advanced signal processing with weak signal amplification and strong anti-interference capability
• Through-type probe design for high sensitivity detection of pipe wall defects
• Automatic detection with high sensitivity and stable performance
• Multiple testing procedures and multi-window display modes
• Fully digital design with standardized testing procedures
• Supports both English and Chinese operation with online help
• Compatible with various probe types (through-type, interpolation, flat, point, rotating)
• Mass storage for test procedures and data
• Optional data analysis system
