LS172B is a handheld multifunctional colorimeter designed with a principle of 45°annular illumination, 0° viewing angle. The instrument is equipped with a 3.5-inch color capacitive touch screen, which provides an excellent operating experience when used alone. The instrument integrates multiple standard color charts, which can quickly match the measured color to the closest color code. The color meter also has a color difference comparison function, supports a variety of standard color addition methods. The color difference threshold can be set and the color difference formulas can be flexibly selected, which can realize rapid QC testing. It support mobile APP, PC software to realize color sharing, data import and export.

Handheld Colorimeter Application

LS172B has a wide range of applications. It is designed with a 45°/0° optical geometric structure. The measured results are closer to visual observations. The equipped mobile App and PC software make the functions more abundant; it is usually used in paint, paper printing, decorations, leather cotton, textile printing, plastics and other industries, for product color management, product color difference quality control and batch inspection.

5. Color scan and color compare

Color measurement can be achieved by pressing the screen or pressing the power button. Measure color in 1 s, compare color difference in 2 steps. Two clicks can complete the color difference comparison, turn on the QC testing function, batch QC testing can be performed. The color difference threshold can be set to quickly achieve quality control. In addition, it provides Lab values of measured color, which makes the color adjustment easier and more convenient.

6. Seven color spaces and six color difference formulas 

The color difference meter has a variety of color spaces such as Lab\RGB\CMYK and a variety of color difference formulas to choose from, matching the color measurement needs of various industries.

7. Create personal color chart, massive storage space

The instrument has built-in large storage space, which can store 1000 colors and 1000 color difference comparison records respectively. By cooperating with mobile APP or PC software, the color meter can store a large amount of data.

8. Support multi-channel color sharing and export

The color data can be imported and exported through mobile APP or PC software. The data can be shared through WeChat, WhatsApp, mailbox, etc. 

9. The latest color sensor

LS172B adopts AS7261 chip-level color sensor newly launched by American AMS company. The precise XYZ tristimulus color sensing function simulates the human eye response curve of the standard observer defined in the CIE1931 and CIE1976 color systems.

10. Compensation optical path technology, whiteboard calibration

The instrument has a built-in compensation optical path with stable values and allows long-period calibration. The bottom cap integrates a calibration whiteboard, so there is no need to worry about losing it. 

11. Provide locating plate to make color measurement more accurate
