Caltech Engineering Services India offers hegman gauge or grind gauge. Hegman gauge is a important tool in measuring parameter of fine solid particle size or thick liquids.
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.Grind Gauge is supplied complete with scraper blade.
Hegman gauges are available in three models 0 to 25 micron, 0 to 50 micron, 0 to 100 micron.
Grind Gauge / Hegman Gauge / Particle Size Gauge is used for the checking and controlling the production, storage, and
application of dispersion products produced by milling in the
paint, plastic, pigment, printing ink, paper, talcum ceramic, pharmaceutical, food, chmicals and many other industries.In operation the samples are placed into the top end of the hegman gauge and then drawn down using the scraper blade.
Hegman gauge or particle size gauge will have one scale marked in either mils or microns. The hegman scale or National standard scale may be abbreviated"NS" on the gage. The scale ranges from 0 to 8 with numbers increasing as the particle size decreases.
0 Hegman = 4 mil/100 micron particle size
4 Hegman = 2 mil/50 micron particle size
8 Hegman = 0 mil/0 micron particle size
Associated standards are: ISO 1524, DIN 53-203, ASTM D1210, ASTM D1316, ASTM D333.
