Precision Grindometer
NK precision grindometers measure the fineness of grinding for paints, coatings, and food or pharmaceutical products. Dual slots and multiple scales ensure accurate, reliable results for quality control.
Ensure accurate paint and coating quality with NK precision grindometers. Ideal for paints, varnishes, lacquers, inks, and even food and pharmaceutical products, these grindometers allow fast and reliable determination of particle size and fineness of grinding.
What is a Precision Grindometer?
A grindometer is an essential tool in quality control for the production of paints, coatings, and decorative laminates. It measures the degree of grinding (grain size or particle fineness) of liquids, ensuring proper dispersion of pigments and uniform coating performance.
Applications include:
- Paint, varnish, lacquer, and ink production.
- Food industry (e.g., chocolate).
- Pharmaceutical industry (e.g., creams).
- Airless spray applications requiring precise nozzle selection.
Key Features of NEURTEK Grindometers
- Material & Durability: Made of hardened stainless steel (AISI-420), corrosion-resistant and maintenance-free.
- Measuring Scales: Equipped with micron scales and Hegman-NS scale for accurate readings; FPVPC scale included in some versions.
- Design Improvements: Two measuring slots for double determination, simplified cleaning, and electrically inscribed scales for easy readjustment.
- Portability: Compact and lighter design with a hardened scraper included in a leather case.
- Versatile Use: Can measure paints, coatings, and non-toxic food and pharmaceutical products.
Measurement Range: Up to 160 mm length with two wide slots. Suitable for high-precision determination of grinding fineness.
Why Measure the Fineness of Grinding?
Measuring grinding fineness is critical for:
- Avoiding films with poor brightness and weak protection due to under-ground pigments.
- Reducing unnecessary grinding costs.
- Determining the most efficient grinding procedure for each product.
- Comparing pigment performance from different sources.
- Outgoing and incoming quality control in factories and for paint consumers.
In short: It ensures rationalized production, consistent quality, and prevents customer complaints.
How to Use a Precision Grindometer
- Pour a few drops of the sample into the deepest part of the grindometer slot.
- Use the scraper at a slight angle to spread the product across the slot.
- Hold the grindometer at eye level and read the scale NS or FPVPC where pigment particles are visible.
- For volatile paints, read within 15 minutes; for synthetic enamels and oils, read within one minute.
Tips for Accuracy:
- Avoid using hot freshly-ground paint on a cold grindometer to prevent coagulation.
- Thin high-viscosity paints with 10–15% high-volatility solvent for smooth readings.
- Paints with spillage time <15 seconds (DIN cup) may not provide precise measurements.
Cleaning and Maintenance
- Clean the grindometer immediately after use with a soft brush and suitable solvent.
- Avoid hard or sharp objects that could damage the measuring surface.
Frequently Asked Questions (FAQ)
