IG-331 Gloss Checker

The IG-331 provides extremely precise measurements at an incredibly low price. Only Horiba®, with their proven record for developing high-performance, innovative glossmeters, could offer the economical IG-331 gloss checker. By defying conventional wisdom, Horiba has once again led the way to produce a gloss checker that is both incredibly inexpensive and incredibly easy to use. Light, compact and incorporating “one-touch” calibration, it is as simple to use as a pocket calculator and it can be used at 20° in addition to the standard 60° measuring angle. The IG-331 brings gloss measurement one step closer to perfection.

What Is Gloss?

Gloss is a quantity that expresses the degree of reflection when light hits a surface. It is determined by comparing the strength of reflected light from the area being measured with that from the standard surface.

What Are the Standards for Gloss?

At an incident angle of 60° on a gloss surface with a refractive index of 1.567, 10% reflectance equals a gloss value of 100, and at an incident angle of 20°, about 5% reflectance is 100, according to JIS.
