The Elcometer 2041 fineness of grind gauges are instruments used to determine the particle size and fineness of grind of many materials including paints, pigments, inks, coatings, chocolates and other similar products.
These two channel gauges, together with the scrapers, are made of hardened stainless steel and have two grooves with a graded slope (dependent on the model chosen). Graduated in microns, mils, NS (Hegman) or PCU (North), the gauges have a tolerance of ±2µm (0.08mil). The groove width for all models is 12mm (0.47") with a groove length of 127mm (5.0").
Elcometer 2041: The basic gauge has lateral graduations engraved on the side of the gauge in mils or microns.
