2.     Product characteristics

(1)   Ultra-high repeatability accuracy:dE*_ab≤0.02

Repeatability accuracy is an important index to describe the accuracy of spectrophotometer.The excellent optoelectronic test system scheme ensures that the repeatability accuracy of TK-70E spectrophotometer reaches a level unmatched by similar productsThe repeatability evaluation standard of TK-70E spectrophotometer adopts strict standards, showing excellent repeatability accuracy.

(2)   Excellent inter-stage consistency:dE*_ab≤0.2

The excellent technology and process level ensure that the TK-70E has excellent consistency between platforms.BCRA series standard color bricks are used for color transfer and color value traceability, which ensures that the same type of instrument still maintains excellent inter-stage difference level between upstream and downstream companies.

(3)   The calibration base and zirconium reference with Mohs hardness of 9 are used to calibrate the instrument, which ensures the long-term stability of the instrument

Compared with the existing products, the TK-70E spectrophotometer does not need frequent manual calibration when it is used. As long as it is placed on the calibration base, the instrument will automatically calibrate the overall instrument function and accuracy according to its own state and environmental factors, ensuring that the instrument is always in a stable state and ready for standby.

The white board in the calibration base is the working basis of the instrument. Through long-term investment and research, the instrument has integrated zirconium material known as "artificial diamond" as a calibration white board, with a surface Mohs hardness of 9. Because the material itself has the hardness and stability comparable to diamond, it can ensure that the surface of the calibration whiteboard will not be scratched and will not change color with the change of temperature and humidity. Compared with foreign and domestic similar products, ordinary industrial ceramics and even plastics are used as the calibration whiteboard, which further improves the stability and durability and ensures the performance of the instrument.

(4)   More than 30 measurement parameters and nearly 40 evaluation light sources are available for selection

TK-70E spectrophotometer provides spectral reflectance, CIE-Lab, CIE-LCH, Δ E * ab, covering power, whiteness, yellowness and other 30+measuring indicators; A. B, C, D50, D55, D65 and other nearly 40 evaluation light sources can be selected, covering almost all color measurement indicators and light source types in the industry.

(5)   The TK-70E supports 12 measurement calibers to choose from

To facilitate user measurement of samples of different sizes, the DS700E spectrophotometer supports 12 calibers for customer use, stable: Φ 11mm+ Φ 10mm+ Φ 6mm+ Φ 5mm+ Φ 3mm+ Φ 1 * 3mm, smart type: ▽ 11mm+▽ 10mm+▽ 6mm+▽ 5mm+▽ 3mm+▽ 1 * 3mm, which can be flexibly applied to various use and test conditions.

(6)   Built-in high-definition camera for clear observation of the tested area

The TK-70E spectrophotometer can obtain images of the tested area throughthe camera during measurement, which can clearly locate the tested area of the sample to avoid inaccurate measurement due to regional errors.

(7)   APPSupport WeChat applet, Android, Apple, and Hongmeng mobile app

l  The TK-70E spectrophotometer can connect various mobile phones through rich mobile terminal programs.

l  Users can easily transfer color data through WeChat without transferring color values and physical objects of samples.

l  Users can find the most similar color in multiple sets of color cards.

l  Users can create a personal color database and enter color card information such as printing, coating, textile, etc. The created color database can be uploaded to the cloud for multi-device data sharing, and color processing is more convenient.

l  Enterprise users can create and manage their own color card information library and color formula in the cloud, and share the information library and color formula with their own users through a unique invitation code.

(8)   Use powerful PC color management system ColorExpert*

 The TK-70E spectrophotometer is attached to the instrument with the Windows color management system ColorExpert, which is connected to the TK-70E spectrophotometer through Bluetooth or USB cable.

ColorExpert is a full-featured color management software with four functional modules: my color, color detection, color matching system, and personal center.

In the "My Color" function module, users can collect or create their own color library in hundreds of color libraries shared by other users. The computer software and mobile APP can share an account, and the color database data follows the account to synchronize the information between the PC and the mobile terminal.

In the "color detection" function module, users can calibrate, measure and set the spectrophotometer through computer software. Users can use the color in the cloud database as the standard sample to measure the color difference, view the spectrum diagram, color difference diagram, standard sample data, and export the desired data test report.

 In the "color matching system" function module, users can be provided with a more convenient and efficient color matching process. After the instrument detects the sample color, the system calculates the formula in the formula center and automatically refines the color, and finally achieves accurate matching. It is suitable for computer automatic color matching applications in paint, coating, printing, textile and other fields.

In the "Personal Center" function module, users can edit their personal information, search or delete the connected instrument information, manage downstream users, and manage the color library shared to downstream users.
