An economical gloss meter which utilizes a separate detector and light source, offers the ability to switch between 60 degree measuring angle for standard gloss measurement, and 20 degree measuring angle for high-gloss surfaces with gloss values over 70. One touch of the calibration key starts the automatic sequential zero-span calibration. Gloss meters reflect light when exposed to a surface. The intensity of this reflected light is measured as gloss. The IG-331 provides a measured value to confirm visual gloss observations reducing human error.
