Technical Data Sheet

Description

DUBL-CHEK Grey Powder No. 6 is a highly refined non-fluorescent grey magnetic powder used for dry method magnetic particle inspection. It is designed to be used in visible light to reveal discontinuities. The particles respond to magnetic leakage fields created by discontinuities in ferromagnetic material. Particles rapidly collect at leakage fields producing grey indications.
