Configuration
- Body (with a micro switch)
- 5Meter power cord(3-core, two-typerubber captire cable)
- Steel carrying case
Features
- AC continuous method achieves higher ability to detect surface defects by the skin effect.
- Yoke method suppresses an electric current flowing directly into the test objects, and avoids the possibility of sparking.
- Small, light, AC 200V or 220V (other voltage option) portable size.
- Any test objects can be inspected with HANDY MAGNA yokes.
- Waterproof switches minimize the risks of layer short or electric shock to human bodies in wet method.
- Type A-1, A-2 and A6 are with potted cable. Tough and waterproof.
