The Model 232 Grindometer according to Hegman, from Erichsen (Germany) was developed to establish the fineness of grind of coating materials.  

The instrument is used to produce a liquid wedge-shaped specimen of the test substance.  It can be easily ascertained by visual inspection where the grain size is larger than the local dimensions of the wedge channel.  

A reading of the channel depth where the boundary between the smooth and the uneven surface areas determines the fineness of the grind.

The Grindometer consists of a block of hardened steel which has been specially treated to ensure dimensional stability. Two precisely defined, wedge-shaped channels are cut into the block. The depth of each channel can be read off micron (μm) scale engraved into one of the longitudinal sides (length 125 mm) of the block. The corresponding Hegman scale (HS) is shown on the opposite side.

 

Standards: ISO 1524, EN 21 524, DIN 53 203, ASTM D 1210.
