Hegman Grindometer

Benefits

• Ensures high precision and consistency in fineness of grind testing.
• Made from corrosion-resistant, hardened AISI-420 stainless steel.
• Compact, lightweight and durable design with a single hardened piece.
• Scale is electronically engraved, easy to read, and includes Hegman-NS and optional FPVPC.
• Two slopes for dual measurement.
• Hardened scraper, leather case, and instruction manual included.
• Compatible with international standards ASTM D1316 and UNE EN ISO 1524.
• Easy cleaning with a cloth thanks to the side scale.
• Simple re-adjustment when the measuring surface becomes worn.
• Avoids defective finishes: Poorly ground paints cause opacity, low gloss and reduced resistance.
• Maximum equipment performance: Adjusts mills and nozzles for more efficient processes.
• Optimises resources: Prevents over-grinding and reduces costs.
• Quality control: Ensures uniformity in laboratories and production lines.
• Pigment comparison: Facilitates the selection of raw materials and consistent batches.

How is the fineness of grind test correctly performed?

1. Place the sample in the deep groove.
2. Slide the hardened scraper upwards.
3. Observe the point where the material stops.
4. Read the value on the Hegman or NS scale.

Benefits of the Hegman grind gauge method

• Evaluates the dispersion of pigments and fillers.
• Allows the grinding equipment to be adjusted for optimum efficiency.
• Facilitates comparison between different pigments or batches.
• It is key in industrial quality control and customer satisfaction.
