A Grindometer is a device used to measure the particle size of suspension, typically inks such as those used in Printing, or paints.

Hegman Gauge Fineness Of Grinding Gauge A Hegman gauge, sometimes referred to as a grind gauge, grind gage, or grindometer, is an instrument which indicates the fineness of grind or the presence of coarse particles and agglomeration in a dispersion.^[1] It is commonly used to determine how finely ground the particles of pigment (or other solid) dispersed in a sample of paint (or other liquid) are. This is important because many types of solid materials must be ground into finer particles in order to be dispersed in liquids.^[2] The resulting properties of the dispersion vary based on the size of individual particles and the degree which they are dispersed.

The Hegman gauge usually consists of a stainless steel block with a series of very small parallel grooves machined into it. The grooves decrease in depth from one end of the block to the other, according to a scale stamped next to them. A typical Hegman gauge is 170mm by 65mm by 15mm, with a channel of grooves running lengthwise, 12.5mm across and narrowing uniformly in depth from 100 μm to zero and used to determine particle size

One of the important parameter in paint evaluation is fineness of grind gauge (hegman gauge) is a precision gauge manufactured from hardened stainless steel and has two ground channels giving scales of both microns and hegman.Supplied complete with scraper blade. Three models are available 0 to 10 micron, 0 to 25 micron, 0 to 50 micron, 0 to 100 micron.

This gauge is used for the checking of particle size in paint or inks and also a wide range of ancillary products i. E. Dyes, talcum, flour, and chemicals etc. In operation the paint / ink samples are placed into the top end of the gauge and then drawn down using the scraper blade. The measurement of either microns or hegman can be made where the coarse particles have been screened out. Associated standards are: iso 1524, bs3900: c6, din 53-203, astm d1210, astm d1316, astm d333.
