น้ำยาผงหมึกแม่เหล็ก สีดำ ขนาด 400 ml.
A highly-sensitive oil-based magnetic particle aerosol for no fluorescent (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.
