Eddy Current


Range of application:
Materials that conduct electricity

Principle of measurement:
The method is based on magnetic induction principles.

Surface faults
Material identification
Coating thickness
Heat damage and heat treatment
Hardening depth

• Reliable, cost effective
• Effective on painted surfaces
• Detects small defects
• Does not require high levels of cleanliness
• Immediate test results, even without direct contact with the material
• Portable equipment, weight ca 1 kg, net or battery run

Limited inspection depth
Rough surfaces may affect the test results
Reference standards are required to set the instrument
Only effective on materials that conduct electricity
Defects such as delamination parallel to the surface are difficult to detect
Requires training and experience to obtain reliable results
