X3-I portable multi-frequency eddy current instrument with full-digital, double frequencies, multi-channel and DSP technologic This intelligent tester is designed for real-time effectively defect detection of metal materials, thickness measurement and sorting materials by metallurgical differences.
　　The X3-I is built in with battery, its weighty is light and size small. X3-I is a multi-purpose instrument, which tests conductive materials using the eddy current test method. Testing capabilities include: tube testing of heat exchangers, weld inspection, assembly line inspection, and other useful broad of eddy current applications. The audio, visual and logic output alarms can determined flaw conditions.
