1. Instant and Precise Color Measurement:Repeatability less than 0.05, display accuracy 0.01, one light press can bring you precise color measurement. 2. Non-contact Auto Calibration:The use of professional non-contact automatic black and white board calibration technology to avoid direct transmission of dirt during the measurement process to the whiteboard, completely solves the problem of separation between the whiteboard and the dust cover required internationally, and ensures the zero position of the whiteboard "this starting line" The long-term accuracy of "makes you more at ease and worry-free when using it." 3. Multifunctional “Smart Button”:The built-in "smart button" of the instrument can independently complete the measurement function setting or test data review. It does not need to connect a mobile phone and a computer. A single machine can realize all the functions of the color difference meter; and at the same time, it can be connected to the mobile phone APP or computer software, taking into account the various functions of the color difference measurement and color management. 4. Professional integrating sphere dual optical path design:Professional advanced integrating sphere coating, dual optical path sensor and full-spectrum light source ensure the stability and accuracy of the measurement results. 5. Diversified Data Display Modes:The ColorReader CR3 with APP can directly display the sample color value, color difference value, pass/fail result, color simulation, color deviation, reflectance and other data, which is convenient for viewing and greatly improves the user's work efficiency.
