WF32 color difference meter caliber 4mm version is a specially designed, high performance precision colorimeter is especially suitable for small area, such as the special surface measurement. In the color quality detection of small devices, small parts, special type of arc to bring great convenience for the user.

For example:
20mm diameter rod plastic product color detection;
Senior glass surface color detection;
Ceramic device with convex, concave security facilities;
The above products color detection in WF32 version of the 4mm help, easily, quickly.
