The Colorimeter is an integral color measuring instrument, which can measure the color data of the reflection or transmission of an object (transmission accessories need to be installed). It can accurately measure various flat, small particle, powder, paste and solution samples. The instrument is widely used in plastics, coatings, textiles, printing, chemical industry, light industry, metallurgy, building materials, medicine, food, home appliances, education, books, cultural relics management and other industries.

Rapid color measurement: using a multifunctional effective processor, the warm-up time takes 5 minutes, and the measurement time is only 3 seconds.
Stable performance: the diffuse reflection integrating sphere is made of special materials, which can ensure the stability and reliability of the color measurement results. The integrating sphere is larger than similar products to ensure that the diffuse reflection of light in the integrating sphere is more uniform.
Optical path reception: Optical fiber with a diameter of 15mm is used for light transmission, and high-precision photocells are used as the receiving end to ensure more accurate and stable measurement results.
Simple operation: Intuitive color touch screen, users can get clear prompts for each step of operation through the display screen, the operation is very simple.
Data management: The instrument presets 3 working files, which can store 600 sets of test data, and can communicate with the computer through the USB interface. In addition, a micro-printer can be connected to print the test results on site.
Easy to use: The instrument is exquisitely designed, and it can be used conveniently in the production workshop or laboratory, which can save you the cost of purchasing multiple sets of instruments.
Personalized design: according to the requirements of special industries, special colorimetric parameters can be added.
The Colorimeter mainly includes four parts: probe, host, power supply and accessories.

Accessories: standard whiteboard, black tube, sample press, powder sample box, USB interface cable, micro-printer (optional), transmission accessories (optional)
