EDDY-CURRENT COMBINED WITH ULTRASONIC TEST EQUIPMENT

EDDY-CURRENT COMBINED WITH ULTRASONIC TEST EQUIPMENT
1.The equipment combining UTD with ETD has complementary advantages. The equipment can improve the defect detectability more effectively.
2.The equipment decreases floor space and operator to improve efficiency.
3.Improve the test quality. Higher performance-price ration.
