Gloss and Haze measurement is essential where an aesthetic appearance of the coating finish is required and to ensure uniformity of the surface finish.
The gloss value is determined by directing a light, which has a similar wavelength to the human eye, at the test surface and
measuring the amount of specular reflection. Gloss is
measured with angles of 60° and 20°. The 60° angle is
universal for all applications. The 20° angle gives improved differentiation of measurement on high-gloss coatings above 70 gloss units.
Haze measurement is required where high-gloss surfaces have
a low reflection contrast. The Haze measurement is the
difference between readings taken with the 20° and 60°
angles, complying with International Standard ASTM D4039. The Stargloss will automatically calculate the Haze reading.
The Haze function is only available on combined 60°/20° models.
Small and portable, the Stargloss is one of the most advanced Gloss Meters available. By using tungsten halogen lamps and
optical filters the light source has a similar spectro-response to the human eye, giving true human photo-optic performance, which is essential for ensuring exact compliance to
International Standards. Optical bench accuracy and stability are obtained by the optics being set in a precision-engineered aluminium block.
Available in models of Standard and Top. All functions are easily accessible through a menu-driven back-lit display.
