PFINDER 115 is a water-suspendible concentrate of fluorescent magnetic particles with special additives for magnetic particle testing. PFINDER 115 indicates surface defects of magnetizable materials under UV-light (365nm).
The concentrate PFINDER 115 has to be stirred in water. An even dispersion of the particles will be obtained very quickly.
The capability of the magnetic particle suspension should be checked regularly by means of own reference pieces or e.g. reference block 1 according EN ISO 9934-3.
