Introduction to colorimeter
The color difference meter is widely used in the color management field of plastics, printing, paint ink, textile and garment industries. According to the Lab, Lch principle of CIE color space, the measurement shows the color difference â–³E and â–³Lab value of the sample and the sample to be tested.
classification
According to the performance parameters, accuracy range and usage requirements, the colorimeter can be divided into:
1, hand-held color difference meter - also known as color color difference meter, can directly read data, can not connect to the computer, without software. Easy to use, cheap, but less accurate. It is widely used in the general field of color management.
2, portable colorimeter - also known as portable spectrophotometer, can directly read the data, but also connected to the computer, with software. Small in size, easy to carry, high precision and moderate price.
3, desktop colorimeter - also known as desktop spectrophotometric color matching instrument, there is a reading window, even when using computer color measurement, color matching software, with high-precision color measurement and color matching function, large size, stable performance, high price .

main feature
1. Automatically compare the color difference between the sample and the tested product, output CIE_Lab three sets of data and colorimetric data of â–³E, â–³L, â–³a, â–³b after colorimetric, and provide a reference scheme for color matching.
2, with sample and single measurement mode to meet the needs of different places measurement, simple operation, accurate measurement.
3. The instrument is portable. There are two power supply modes, battery and external power supply, which are convenient and practical.
4, installed with the USB expansion interface, you can connect to the computer display.
How the colorimeter works
Automatically compares the color difference between the template and the tested product, and outputs three sets of color data of L, a, b and colorimetric data of ΔE, ΔL, Δa, and Δb after colorimetry.
â—†E total color difference
â—†L large means white, â–³L small means black
â—†a large means reddish, â–³a small means greenish
â—†b large means yellowish, â–³b small means bluedish
The color difference meter can meet the needs of plastics, coatings, textiles, scientific research, medicine, food and other industries to analyze and control various production process quality, incoming material quality and quality assurance work.
How to use the colorimeter
1. Remove the lens protection cover.
2. Turn on the power supply to the ON position.
3. Press the sample target button TARGET and the Target L ab is displayed.
4. Press the lens button to align the measured part of the sample, and press the record button. After the sound of “嘀â€, the lens can be removed. The correct value of the sample is displayed: Target L**.* a +-**.* b +-**.*.
5. Align the lens with the part to be tested and repeat the test at point 4. The color difference between the item and the sample is displayed: dL**.* da +-**.* db +-**.*.
6. According to the working principle described above, the color difference and the color cast direction between the two are determined by dL, da, and db.
7. Repeat steps 6 and 7 to repeatedly check the color difference between the other tested items and the fourth point sample.
8. To resample, you need to press TARGET, starting at 4 o'clock.
9. After the test, cover the lens protection cover and close the power supply.
Application field of color difference meter
Precision colorimeter is mainly used for color matching of color systems such as clothing, home, architecture and interior decoration. Suitable for use in design, printing, clothing, printing and dyeing industries. The instrument is easy to use, greatly improving work efficiency and reducing communication costs. The instrument can be used to measure the color of various colors, can accurately measure the color of CIE_Lab, CIE_XYZ, CIE_xyY, RGB, etc., directly display the color difference between the two samples. The instrument is powered by a 9V battery (also available with an external 9VDC power supply), which is small in size, light in weight and easy to operate. It can detect the color of any smooth surface, stable performance and accurate and reliable measurement results.
Fully automatic color difference meter: All Chinese display, Chinese prompts can be given for various operations, easy to use, wide application range.
Swift PRO is the upgraded version of swift series, but it has the following advantages:
1. Super fast charging: maximum 50A (The battery is less than 50C, using EV-PeakU6Q smart balance charger).
2. Charge time: 400.
3. Fast heat dissipation. Although after using, the outside of the battery seems high temperature, the internal cells remain stable at the bottom and can be checked by the battery tester.
4. Improve work efficiency. The temperature of Swift PRO battery will not rise more than 6℃ after discharge, even with large electric current.
5. It has better waterproof ability.
6. Have a better user experience.
7. Improve BMS, have higher accuracy.
