HunterLab offers a selection of instruments to help you manage your concrete and cement color measurement and quality control requirements.
70% of our customers choose a directional 45°/0° geometry instrument as a QC tool for its ability to measure color the way the human eye sees color, capturing both the effect of color and the effect of gloss and texture. This is the geometry that is recommended by HunterLab for color measurement of opaque finished materials that will be viewed by the customer.
30% of our customers choose diffuse d/8° Sphere geometry for measuring color for its tendency to negate surface appearance attributes of gloss and texture and look at color only.
