Three popular domestic (CN) Colorimeters contest

Colorimeters can be divided into handheld Colorimeters, portable Colorimeters, and desktop Colorimeters according to their appearance and shape. The color measurement principles mainly include tristimulus value type and spectroscopic type.

The editor today introduces several domestically produced Colorimeters with the same tri-stimulus value-based color measurement principle, including Sanenchi, Weifu, and Jinzhun, all of which can measure flat, concave, and arcuate surfaces. However, in terms of size and weight, Sanenchi is larger in size but lighter, while Weifu is smaller in size and more comfortable to hold, but it is the heaviest among the three. The detailed parameter comparison is shown in the table below:
