Description
The TQC Sheen Grindometers (also known as a fineness of grind gauge) is a simple, reliable inspection tool used to evaluate the dispersion quality and particle size distribution in liquid coatings, paints, inks and similar formulations. By measuring the maximum particle profile height across a set of calibrated steps, this gauge helps determine grind or dispersion fineness — a critical parameter in quality control and formulation processes.
Grind gauges provide rapid, visual assessment of dispersion consistency, helping manufacturers monitor product stability, batch uniformity and optimal pigment wetting. This tool is essential in coating laboratories, production lines and quality control environments for consistent quality assurance of paint and coating products.

How It Works
- Select the appropriate gauge scale based on your test method or formulation requirement.
- Place a small amount of sample between the instrument’s notched measurement scale.
- Draw scraper across the gauge, ensuring the sample fills the notches.
- Visually inspect the filled steps and identify the highest step that is completely filled without voids.
- Record the corresponding channel number or micron value as the fineness of grind.
- Compare readings against internal specifications for quality control.
This direct, visual method allows quick evaluation of particle dispersion quality without complex instrumentation.
