A simple and easy-to-use instrument to measure the fluidity of a coating.

The product to be measured is poured into a semi-spherical cavity of the instrument, which is in the horizontal position. The instrument is then lifted vertically allowing the liquid to flow under gravity, in the groove, which is graduated in mm.

The distance it flows after approximately 10 seconds ±0.5 seconds, measured with the sand timer provided, indicates the fluidity of the coating.
