7HF black oil magnetic suspension

7HF is a high-sensitivity oil-based magnetic suspension in a spray can for non-fluorescent wet magnetic particle detection. 7HF is suitable for detecting small and medium discontinuities on finished products, and can form a clear indication of defects. 7HF is suitable for on-site inspection, spot check and other places where it is inconvenient to use bulk magnetic suspension.

7HF is usually used in conjunction with WCP-2 contrast enhancer to improve contrast and detection sensitivity. Suitable for field inspection, such as pipelines and large structural parts.
