The Horiba IG-331 Gloss Checker is an economical gloss meter. It measures 60° and 20° Angles and features a display range of 0-199 Gloss Units (GU) with a 1 GU Resolution.
The 60 degree measuring angle is for standard gloss measurement, while the 20 degree measuring angle is 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.
Additional Functions Include:
Automatic calibration
Automatic power cut-off
Display hold
Overrange display
Battery life display
