Hegman Gauge Stainless Steel 0-150μm Paint Ink Fineness

Product Features & Attributes
This Hegman gauge (fineness gauge, grindometer) is used to determine the dispersion fineness of pigments and impurities in paints, pastes, inks and other liquids or pastes. It is common quality control testing equipment in paints, inks, plastics, ceramics, pharmaceuticals, food and other industries.

Working Principle: Place the sample at the bottom of the groove on the fineness gauge. Draw the scraper from the bottom of the groove at the appropriate angle and speed. Observe the scale position where significant speckling appears on the sample surface. The reading indicates the depth of grinding particles at the discernible level.

Structural Features:

• Made of high-grade stainless steel wear-resistant material for durability

• Smooth and flat surface with high precision

• Includes dedicated scraper for easy operation

• Four range specifications for different fineness levels

Four Range Specifications Available:

• 0-25μm: For high fineness samples, scale division 2.5μm

• 0-50μm: For medium fineness samples, scale division 5μm

• 0-100μm: For general fineness samples, scale division 10μm

• 0-150μm: For coarse particle samples, scale division 10μm

Operation Steps:

1. Ensure sample is dry and clean, place at groove bottom

2. Hold scraper with both hands, draw from groove bottom at appropriate angle

3. Apply sufficient downward pressure to fill the groove with sample

4. Observe and record fineness value at appropriate angle immediately

5. Count particles in 3mm wide groove (5-10 particles), take the higher scale reading

6. Clean immediately after use

Maintenance:

• Avoid impact to gauge surface and scraper edge

• Clean and apply anti-rust oil after use

• Check flatness annually

• Accuracy guaranteed at 22±1℃, 70% RH

Applications:

• Paint industry: Paint paste fineness testing

• Ink manufacturing: Printing ink dispersion control

• Plastics: Pigment dispersion quality evaluation

• Ceramics: Glaze fineness testing

• Pharmaceuticals: Paste fineness control

• Food: Slurry fineness analysis

Available in four range specifications (0-25μm, 0-50μm, 0-100μm, 0-150μm), single/double groove design, and different scraper sizes to suit various industries and testing standards.

Mainly used in paint manufacturers, ink manufacturers, plastic product factories, ceramic manufacturers, pharmaceutical manufacturers, food processing companies, quality inspection institutions, research universities, and more.
