The color difference meter is mainly used to measure the color difference. With the continuous development of the market economy, the color difference meter is widely used in all walks of life. Generally, Colorimeters are divided into portable and desktop Colorimeters according to their appearance, and are divided into tristimulus type and spectroscopic type according to their principles.
This article introduces the two Colorimeters of Donghong DR-10 and Sannchi SC-10. The DR-10 color difference meter adopts 8mm general-purpose measurement caliber and is widely used in various industries. Sannchi SC-10 is handheld Type Colorimeter, measuring aperture is 4mm, with light positioning and cross positioning, suitable for some small area measurement.
The detailed parameter comparison is shown in the table below:
