LS171 colorimeter is a new instrument to provide color measurement and stable color comparisons for materials and products wherever color control is important. The instrument complies with relevant international CIE standards and GB standards. It adopts D/8 optical structure and is equipped with a high-precision sensor that complies with CIE. The instrument has good consistency and repeatability. LS171 colorimeter can be used with mobile APP for accurate color measurement and quality control. It is widely used in plastics, paint, printing, ceramics, textiles, automobiles and other industries. The instrument can restore the color of the collected sample and identify color difference. Using this affordable instrument will boost your color quality when color requirements are too stringent to depend on visual evaluation alone. It is more accurate and reliable than other basic colorimeters. It is a high-precision colorimeter with outstanding comprehensive functions and extremely cost-effective.


As a portable colorimeter, LS171 is widely used in car paint spraying, test paper printing, leather fabrics, plastic metal, textile and clothing, hardware, furniture industry, plastics, rubber and other fields.

LS171 Colorimeter Characteristics

  1. Achieve stable color quality with the help of QC testing function when measuring color difference, after customizing the color difference threshold (tolerance value), it can automatically judge whether the color difference is qualified. The handheld colorimeter will also show the color cast direction.

  2. We can enter the Lab, LCh values of the standard color in the color compare interface and measure the standard color then save it in the colorimeter App. Standard color can also be added from the personal color chart and standard color chart without standard and the sample.

3. Collect favorite colors anytime and anywhere. It can intelligently match multiple standard color charts and the matching accuracy of the color charts is greater than 90%. The mobile APP interface can directly restore the collected colors. Before we take the color measurement, we can select the color chart that we need first,  such as Pantone color chart.
