Introduction
ColorReader CR2 is developed by 3nh using a combination of professional color sensor and performance-rich APP application, specially set up a multi-functional "smart button" and professional non-contact automatic whiteboard verification, realizing the two-in-one of micro Colorimeter and mobile phone. It is often used in plastic electronics, paint and coating, textile and garment printing and dyeing, ceramics and other industries for color difference quality control. Compact and portable, the CR2 can be used to capture color inspiration anytime and anywhere after being wirelessly connected to a mobile phone device, in addition to color measurement, Color Chart recognition and search, and a variety of functions can be expanded.
Features
1. Real-time and accurate color measurement
With repeatability of 0.08 or less and display accuracy of 0.01, it gives you accurate color measurements with just one touch.

2. Non-contact automatic calibration
The professional non-contact automatic black and white board calibration technology is used to avoid the dirt in the measurement process from being directly transmitted to the whiteboard, which effectively solves the problem of separation of the whiteboard and the dust cover required by the international requirements, and ensures the long-term accuracy of the whiteboard "zero position of the starting line", so that you can use it more assured and worry-free.

3. Multi-functional "smart button"
The instrument comes with a "smart button", which can independently complete the measurement function setting or test data search, without connecting the mobile phone and the computer, the single machine can realize all the functions of the Colorimeter, and at the same time connect to the mobile phone APP or computer software, and can take into account the various functions of the color difference treasure and color management.

4. Professional integrating sphere double optical path design
Professional advanced integrating sphere coating, dual optical path sensors, and full-spectrum light source ensure the stability and accuracy of measurement results.

5. Lightweight and portable
Fits easily in your pocket, takes you with you wherever you go, and measures hassle-free.
6. Rechargeable lithium battery
Type-c interface, 12,000 times of continuous testing at a single full charge.

7. Higher quality
Using industrial-grade real-time processing MCU, Bluetooth interface 5.0 transmission is more stable and reliable.
8. The data display mode is diversified
ColorDifference CR3 can intuitively display the sample chromaticity value, color difference value/figure, pass/fail results, color simulation, color bias, reflectance and other data with APP, which is convenient to view and greatly improves the user's work efficiency.
9. Carry a massive Color Chart database
APP synchronous mass storage, can quickly carry out color data search, analysis and comparison.
Use the App to build your private color database in the cloud, you don't need to carry a heavy Color Chart, you can use CR3 Colora Treasure to find the most similar colors in multiple Color Charts anytime and anywhere.
