Product Description:
Qualtech Products Industry precision Automatic Fineness of Grind Tester brings a new level of accuracy, consistency, and speed to particle size evaluation. Traditional grind‑gauge testing relies heavily on operator technique — variable scraping force, inconsistent speed, and subjective visual judgment. This instrument eliminates all human variability by combining robotic motion control, high‑resolution imaging, and deep‑learning particle recognition into one seamless, fully automatic workflow.
Designed for laboratories that demand repeatability, traceability, and ISO‑1524‑compliant results, this system delivers a complete fineness measurement in seconds — with image capture, particle analysis, distribution statistics, and final grading all performed automatically.
This professional Automatic Fineness of Grind Gauge delivers Precision Particle Size Measurement - Fully Automatic. ISO -Compliant. Engineer‑Approved.

Automatic Fineness of Grind Gauge QPI‑AGM2800 - Features:
The Fineness of Grind Test Method determines the particle size and dispersion quality of pigments, inks, coatings, chemicals, and related liquid or semi‑liquid formulations. The test evaluates how finely solid particles are dispersed within a vehicle system by visually identifying the point at which particles become detectable on a standardized Fineness of Grind Gauge.
The Automatic Grindometer QPI‑AGM2800 performs this test with a fully automated, electronically controlled blade motion to ensure maximum accuracy, repeatability, and operator‑independent consistency.
Test Principle
A defined amount of sample is applied onto the surface of a Fineness of Grind Gauge (Single Channel, Double Channel, Wide Channel, Hegman, NPIRI, etc.). The gauge features a precision‑machined channel with a depth that gradually decreases from a maximum value to zero.
During the test:
The Grindometer Blade moves across the gauge surface.
As the channel becomes shallower, larger particles begin to appear as streaks or scratches.
The position where particles first become visible corresponds to the fineness of grind or particle size of the sample.
This visual evaluation is the globally accepted method for determining dispersion quality.
Automatic Test Procedure with QPI‑AGM2800
The QPI‑AGM2800 enhances the traditional manual method by performing the blade motion automatically with:
Preset speed
Preset test load
Preset blade angle
Electronically controlled linear motion
This eliminates operator‑dependent variations such as:
inconsistent blade pressure
uneven blade angle
fluctuating speed
differences between operators
fatigue or manual handling errors
The result is significantly increased accuracy, higher repeatability, and consistent test results across all operators and test series.
How the Automatic Grindometer Improves the Method
The QPI‑AGM2800 integrates:
precision microchip control
a high‑accuracy motor drive
adjustable test load settings
a large backlit LCD display
open sample area compatible with most existing Fineness of Grind Gauges
robot‑arm‑like mechanics ensuring identical blade motion every time
This ensures that every test is performed under identical mechanical conditions, providing laboratory‑grade consistency and eliminating human variability.
Suitable Sample Types
The Automatic Grindometer is ideal for:
paints & coatings
inks & pigments
varnishes
chemicals
pharmaceuticals
food products
chocolate & confectionery suspensions
cosmetic dispersions
and related liquid or semi‑liquid formulations
