Gloss Checker IG-331

Designed for greater ease of operation, maintain clean surfaces and improve quality control inspection in various industrial applications.

High efficiency and flexibility utilizing 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.

The flexible connection between the probe and display unit ensures greater work efficiency.

Just one touch of the calibration key starts the automatic sequential zero-span calibration.
