Introduction
Color Colorimeter DR-11 is independent property rights of the domestic (CN) economic Colorimeter, with accurate data, simple operation, easy to carry and other advantages, low power design 3200mAh large-capacity lithium battery to ensure that the instrument can measure for a long time, with CQCS3 quality management software, the user's color management in the PC computer side data, compare color differences, generate test report forms, convenient for customers of high-level color management work.
Product Applications
The color Colorimeter DR-11 adopts a general-purpose measuring aperture of 8mm, which is widely used in plastics, electronics, paints, inks, textile and garment printing and dyeing, printed paper, automobiles, cosmetics and food. SCI supports a variety of sample measurements, accurate data, easy to use, and is a practical tool for color detection in production, quality control, etc.
Features
1. Automatic correction at start-up, faster and more accurate measurement
The display accuracy is 0.01, and the repeatability measurement accuracy can be controlled within 0.03
2. A variety of color measurement space, a variety of observation light sources
The DR-12 provides CIE LAB, XYZ, LCh, CIE RGB, CIE LUV color space, as well as D65, A, C, D50, F2, F6, F7, F8, F10, F11, F12 observation light sources, which can meet the special measurement needs under different measurement conditions.
3. Ergonomic design
The DR-12 has a beautiful, smooth shape and comfortable grip, conforms to the structural design of ergonomics, fits the palm of the hand and is suitable for continuous detection work, allowing you to use it quickly and easily.
4. Dual-aperture fast switching, adapting to more samples to be measured

5. Precise positioning of light positioning and cross, which can quickly align the measured part
The color Colorimeter DR-12 uses light positioning technology (patent number: ZL201120566485.2) and cross precise dual positioning, which can quickly align the position of the measured object, achieve accurate positioning measurement, and improve measurement efficiency.

6. ETC real-time calibration technology
In addition to the standard whiteboard correction function, the DR-12 also adopts the innovative ETC real-time calibration technology (Every Test Calibration), and the standard whiteboard is built into the optical system to ensure reliable accuracy and repeatability in every test.
7. Color management software
The portable Colorimeter DR-12 is equipped with CQCS3 quality management software, which is suitable for quality monitoring and color data tabular management in various industries. The user's color management is digitized on the PC side, the color difference is compared, and the test report form is generated, which is convenient for the customer's high-level color management work.
