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.
- Particles are easily agitated, fast acting and produce defined indications
- Particles meet specification requirements
- Can be used with both stationary and portable magnetic test equipment
- Can be used at elevated temperatures
- The grey colour gives a clear contrasting colour to backgrounds
