Roofing materials come in many forms, from traditional asphalt shingles to modern painted metal, from ceramic to formed clay and terracotta. Due to the wide variation of these materials and applications, HunterLab offers several choices of color measurement instrumentation, for both laboratory use and in-process in the production environment.
95% of our customers choose a 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 end user.
Many of HunterLab's spectrophotometers are versatile enough to accommodate most applications of color measurement. However, based on 60+ years of experience and a thorough understanding of our customers' needs and product use, these particular instruments are most suited for this industries application.
If you are unsure which instrument type is right for your samples, please call or email HunterLab technical support and we will be happy to assist you in making the proper instrument selection.
