LS170 is a portable intelligent APP Colorimeter for color acquisition and color contrast comparison, which is widely used in the ink printing industry. The instrument is equipped with a powerful mobile phone app, which uses a data-based method to quickly achieve color measurement and color difference comparison! The mobile app is equipped with a number of international standard color libraries, which can quickly match the Color Chart number close to it when color collection, and can store the collected colors to establish a personal color library; The collected color and color difference comparison results can be shared through WeChat, QQ, email and other tools.


1. The instrument has the function of QC quality inspection, and the threshold (tolerance value) of the qualified judgment can be manually set to intelligently determine whether the color difference is qualified.

2.APP has multiple standard electronic Color Charts, and the instrument measurement speed is fast, and it can quickly match the color number that is close to it. The accuracy rate is up to 90%, and there is no need for heavy Color Charts.
3. It can store massive color data and collect the desired color anytime and anywhere.
4. The instrument can import color data, and the data can be shared through WeChat, QQ, email and other software.
5. 7 color spaces, 6 color difference formulas to choose from, to meet the testing needs of different industries.

6. The volume is as small as lipstick, and it is easy to carry.

7. Support Chinese and English bilingual, after the mobile phone system is set to a foreign language, the APP can be automatically converted to English.
8. The product has a built-in rechargeable lithium battery, ultra-low power consumption, and can be continuously measured 10,000 times when fully charged.
9. There is no need for cumbersome black and white board calibration, and the built-in compensation optical path makes the measurement data stable, and there is no need for frequent calibration.
10. The color of the standard sample can be added, and a personal Color Chart library can be established to meet the comparison of the color difference of the product when there is no physical sample.
11. The standard deviation of the instrument is within △E*ab, within 0.03, and the repeatability is good.
12. The product body is stable and the measurement data is stable.
