Precision DS-620The spectrophotometerProduct Features

1. Repeatability accuracy: dE * ab ≤ 0.02

Repetitive accuracy is an important indicator for describing the accuracy of a spectrophotometer. The excellent optoelectronic testing system scheme ensures repeatability accuracy, reaching a level that is difficult to compare with similar products. The repeatability evaluation standards adopt strict standards.

2. Excellent inter platform consistency

Ensuring excellent inter platform consistency. The use of BCRA series standard color bricks for color transfer and color value traceability ensures the excellent inter table difference level of the instrument.

3. The calibration base and zirconium reference with a Mohs hardness of 9 are used to calibrate the instrument, ensuring its long-term stability

When in use, there is no need for frequent manual calibration. As long as it is placed on the calibration base, the instrument will automatically calibrate its overall function and accuracy based on its own status and environmental factors, ensuring that the instrument is always in a stable state and ready for use at any time.

The whiteboard in the calibration base is the working foundation of the instrument. Integrated zirconium material known as "artificial diamond" as a calibration whiteboard, with a surface Mohs hardness of 9. Due to the material's hardness and stability comparable to diamonds, it ensures that the calibration whiteboard surface will not be scratched and will not change color with temperature and humidity changes. Compared to similar foreign and domestic products that use ordinary industrial ceramics or even plastics as calibration whiteboards, it further improves stability and durability, ensuring the performance of the instrument.

4. Supports 3 measurement calibers to choose from

In order to facilitate users in measuring samples of different sizes, three calibers are supported for customers to use: Φ 8mm/11mm, Φ 4mm/6mm, and Φ 3mm, which can be flexibly applied to various usage and testing conditions.

5. More than 30 measurement parameters and nearly 40 evaluation light sources to choose from

Provide spectral reflectance, CIE-Lab，CIE-LCh，ΔE*ab， Covering power, whiteness, yellowing and other 30+measurement indicators; A. Nearly 40 evaluation light sources, including B, C, D50, D55, D65, etc., can be selected, covering almost all color measurement indicators and light source types in the industry.

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

During measurement, the image of the measured area can be obtained through the camera, which can clearly locate the measured area of the sample and avoid inaccurate measurement caused by area errors.

7. Support WeChat mini programs, Android, Apple, and HarmonyOS mobile apps

Various mobile phones can be connected through rich mobile applications.

Users no longer need to transmit the color values and physical objects of samples, and can easily transmit color data through WeChat.

Users can search for similar colors in multiple color cards.

Users can create a personal color database and input color card information for printing, coatings, textiles, etc. The created color library can be uploaded to the cloud for multi device data sharing, making color processing more convenient.

Enterprise users can create and manage their own color card information database and color formulas in the cloud, and share the information database and color formulas with their users through invitation codes.

8. Use the PC color management system ColorExpert*

The instrument comes with the Windows color management system ColorExpert, which can be connected via Bluetooth or USB cable.

ColorExpert is a fully functional color management software with four major modules: My Colors, Color Detection, Color Matching System, and Personal Center.

In the "My Colors" function module, users can bookmark or create their own color library from hundreds of color libraries shared by other users. Computer software and mobile apps can share accounts, and color library data follows the account to achieve information synchronization between PC and mobile devices.

In the "Color Detection" function module, users can calibrate, measure, and set up the spectrophotometer through computer software. Users can use the colors in the cloud database as reference samples to measure color difference, view spectra, color difference maps, reference sample data, and export desired data test reports.

In the "Color Matching System" function module, users can be provided with a more convenient and efficient color matching process. After the instrument measures the color of the sample, the system calculates the formula in the formula center and automatically adjusts the color to achieve precise matching. Suitable for computer automatic color matching applications in fields such as paint, coatings, printing, and textiles.

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