Surface Profile Gauges are used to measure the profile heighsdgdsfgsdgggggggggggggggggg overall volume of coatings used. If the surface profile is too large the amount of coating required increases, otherwise there is a danger that the peaks remain uncoated – allowing rust spots to occur. If the surface profile is too small there may be insufficient key for adequate adhesion leading to premature coating failure.
The Elcometer 123 Profile Gauge measures the peak-to-valley height of a blast cleaned surface in a similar way to the Elcometer 224 Digital Surface Profile Gauge.
The Elcometer 123 Profile Gauge can be used in accordance with:
