R4 An User Friendly Color Reader
◆The instrument itself has a data review function
◆Automatic calibration at startup, no need for tedious instrument calibration; combination of professionalism and meticulousness, equipped with manual calibration function of black and white board. It is recommended that users do simple professional calibration by themselves from time to time to ensure that the instrument always works in a state where it can pass the metrology.
◆The mini whiteboard is inserted into the instrument bag, and the whiteboard is separated from the instrument, which ensures the weather resistance, dirt resistance and wipeability of the whiteboard, and guarantees the standard baseline function of the whiteboard for a long time.
◆Equipped with a tightly buckled dust-proof cover with a delicate touch and an environmentally friendly packaging cloth bag that can be easily carried by hand. Close the cover and power turns off. Easy to carry aroud, you can put it in your car, your bags, or just carry it. It's really conspicuous, safe and reliable.
◆Long battery life, convenient USB port charging and power bank charging. It can measure thousands of times in the screen state of high brightness, and it can measure tens of thousands of times when the screen is turned off.
◆The large screen of the instrument and the mobile phone software display have the simulation function of true color
Convenient Color Difference Measurement
◆It can measure the color parameters of objects, such as L*a*b, L*C*H, RGB, Hex, etc. under D65 and other light sources
◆ΔEab, ΔE00 color difference display, flexible setting of tolerance range prompt
Mobile Color Card Database
◆You can use ColorReader to build a personal color database in the cloud
◆There is no need to carry heavy color cards, you can use ColorReader to find similar colors in various color card databases anytime and anywhere
Function of Searching Popular Color
◆Connect the mobile phone APP, measure the color, and search in the color card database
◆Automatically match the latest popular colors (Besides traditional color cards, ColorReader will release and recommend fashionable international colors from time to time)
◆ColorReader has only a slight difference between each instrument in the same series of products. The APP will automatically identify the instrument model and share the color database to ensure the good ecology of the instrument.
