# Grindometer acc. to Hegman Model 232

## Grain Size

The Model 232 Hegman Grindometer is used to determine the ground fineness of coating materials. A liquid wedge of the test substance is generated on the testing device. If the grain dimensions are larger than the local wedge thickness, this is easily detected visually. At the boundary between the disturbed and smooth liquid surface, the operator can read the associated wedge thickness, this value refers to the fineness of grinding.
