CircleSafe® 820A is a nonfluorescent (visible) wet method magnetic particle inspection aerosol spray made up of extremely sensitive Mi-Glow® 106 black particles, premixed with our advanced liquid water conditioning agent, Wetting Agent 771, formulated in water media. It is designed to be used with visible light for a nonfluorescent wet method magnetic particle inspection of discontinuities found in the NDT of finished surfaces, structural fabrications, and welds. Higher particle concentration provides a clear and well-defined indication buildup for easy detection.  The water conditioning agent #771 offers best in class wet magnetic particle coverage on the inspection surface and has the necessary corrosion inhibitors and conditioning agents for a successful water based magnetic particle inspection. Use with Mi Glow® White Contrast Paint (WCP) for an enhanced and more sensitive wet method magnetic particle testing result. Along with the other water based magnetic particle inspection aerosols in the CircleSafe® product line, the CircleSafe® 820a is packaged with a carbon dioxide propellant for an odor-free, fume-free, non-combustible, and SAFE magnetic particle inspection.

7HF – A highly-sensitive oil-based magnetic particle aerosol for nonfluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts.

7HF provides clear, strong indications due to the heavy buildup of the highly magnetic particles. The convenient aerosol packaging is ideal for field testing, spot inspections and places where bulk processing is impractical, and the wide spray pattern makes it easy to cover large areas for faster processing during remote inspections of tubing, piping and large structures.
