1. Instant and Precise Color Measurement:Repeatability less than 0.08, 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 to 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. Higher Quality:Using industrial-grade real-time processing MCU, Bluetooth interface 5.0 transmission is more stable and reliable. 5. Massive Color Card Database with You:APP synchronizes mass storage, which can quickly check color data, analyze and compare. Use the App to build your private color database in the cloud, without having to carry heavy color cards, you can use CR2 to find the closest color among multiple color cards anytime and anywhere.
