LS170 Colorimeter Characteristics

1. Achieve stable color quality using QC testing function when making color comparisons, after customizing the color difference threshold (tolerance value), it can automatically judge whether the color difference is qualified. The color cast direction is also displayed in the right of the ΔE value.

2.If you do not bring standard and sample, you can add the colors of the standards and samples into the personal color chart and standard color chart. In the color compare interface, we can directly input the standard color data such as LCh values and Lab values to compare with the sample color. You can also measure the standard color and save it in mobile colorimeter App.

3. Multiple standard color libraries are stored in the mobile APP, the small colorimeter has fast measurement speed and can quickly match the color close to it. The accuracy rate is as high as 90%, heavy color cards are unnecessary.

4. A large amount of color can be stored in mobile APP and make color measurement anytime and anywhere. Before measuring the color, we can select the color chart we need first.

5. Import and export color data via QQ, WeChat, email and other software.

6. LS170 portable colorimeter has 7 color spaces and 6 color difference formulas to meet the needs of different industries.
