TW-DS-700E Handheld Portable Spectrophotometer Coating Plastic Automotive Textile Color Analyzer

Description :

　　TW-DS-700E portable spectrophotometer product details:

　　1. Core technology

　　(1) Dual light path design improves repeatability accuracy with dE * ab ≤ 0.02

　　The dual path design monitors the energy fluctuations of the light source while measuring the sample signal, reduces interference during measurement, achieves measurement stability, and improves the instrument's measurement repeatability index to dE * ab ≤ 0.02. Ensured the standards for instrument, measurement speed, accuracy, stability, and inter platform consistency.

　　(2) Concave grating optical path structure

　　The use of concave gratings to achieve spectral capabilities better than 10nm has improved the technical performance of the product.

　　2. Product features

　　(1) High repeatability accuracy: dE * ab ≤ 0.02

　　Repetitive accuracy is an important indicator for describing the accuracy of a spectrophotometer.

　　(2) Inter station consistency: dE * ab ≤ 0.2

　　The BCRA series standard color bricks are used for color transfer and color value traceability, ensuring the 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

　　The spectrophotometer does not require frequent manual calibration during use. As long as it is placed on the calibration base, the instrument will automatically calibrate its overall functionality and accuracy based on its own state and environmental factors, ensuring that the instrument is always in a stable state and ready for use.

　　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.

　　(4) More than 30 measurement parameters and nearly 40 evaluation light sources to choose from

　　The spectrophotometer provides spectral reflectance, CIE-Lab，CIE-LCh，ΔE*ab， Covering power, whiteness, yellowing and other 30+measurement indicators; A. There are nearly 40 evaluation light sources to choose from, including B, C, D50, D55, D65, etc.

　　(5) Supports 12 measurement calibers to choose from

　　In order to facilitate users in measuring samples of different sizes, the spectrophotometer supports 12 different calibers for customers to use. The stable type is Φ 11mm+Φ 10mm+Φ 6mm+Φ 5mm+Φ 3mm+Φ 1 * 3mm, and the flexible type is ▽ 11mm+▽ 10mm+▽ 6mm+▽ 5mm+▽ 3mm+▽ 1 * 3mm, which can be applied to various usage and testing conditions.

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

　　The spectrophotometer can obtain an image of the measured area through the camera during measurement, 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

　　·The spectrophotometer can be connected to various mobile phones 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 and convenient color processing.

　　·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) The PC color management system ColorExpert used*

　　The spectrophotometer comes with the Windows color management system ColorExpert, which can be connected to the spectrophotometer 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 convenient 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 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.
