LS173 is a portable multifunctional colorimeter with D/8° optical geometry design. The color analyzer is equipped with a 3.5-inch IPS color capacitive touch screen, which has an excellent operating experience. The colorimeter integrates multiple natural color charts, which can quickly match the measured color to the closest color codes. The color difference meter also has a color difference comparison function, supports a variety of standard color addition methods, the color difference threshold can be set. The color difference formula can be flexibly selected, which can realize rapid QC testing.

Colorimeter Application

LS173 adopts D/8° specular component include (SCI) and the measured result is closer to the actual color of the object. Usually used in automotive paint, metal processing, stone, ink printing, decorative materials, leather cotton, plastics and plastics industries for product color measurement and management, product color difference quality control. The colorimeter is illuminated by an integrating sphere diffused light source, which is very suitable for color measurement of high-gloss and textured samples.

2. precautions

  • When the colorimeter has not been used for a long time, it is recommended to perform calibration before using.

  • Please ensure that the sample is evenly colored with a flat and clean surface, otherwise it will affect the measurement accuracy.

  • After the base is removed from the host, it should be stored in a clean place to avoid contamination of the standard tile.

  • Do not insert any object inside the colorimeter to clean it, as this will damage it and affect measurement accuracy and operational safety.

  • Charge the colorimeter in time when the battery is out of power.

  • If not in use over 6 months, charge it regularly to prevent the battery from over-discharge and damage.

  • It's recommended to calibrate the instrument once each year. And we offer calibration service.

  • Due to different mobile phone displays, there may be a slight color difference between the actual color and the color displayed on the mobile phone App.
