BB20 Coating Thickness Gauge
The innovative BB20 with two sensors allows for the measurement of the thickness of non-magnetic coatings (e.g., paint, varnish, plastic coatings, galvanized coatings, enamel, or chrome plating) on both iron or steel and non-ferrous metals such as aluminum, magnesium, titanium, etc.
The measuring tip features a spring and a practical V-groove. This simplifies measurement on round objects, such as shafts or hinges, and ensures that vibrations do not affect the measurements.
This measuring device, which can be conveniently operated with just one hand, impresses with a wide measuring range of 0 to 1250 µm and ensures accurate results in every situation thanks to helpful statistical indicators and a practical alarm function when layer thicknesses exceed or fall below freely definable thresholds.
Its professional features make the BB20 an indispensable tool in the automotive industry—for example, for measuring paint colors or detecting repainted accident damage— as well as for the universal inspection of fence and marine paints or other protective coatings.
