WS-420Series neutral professional spectrophotometer

Professional version spectrophotometer WS-420 series develops new color measurement skills for colorimeters; Built in camera, measure wherever you want; Equipped with a UV light source to achieve fluorescence color measurement; Connect to a mobile app, unlimited data measurement and storage, multiple sets of color card information, and search for similar colors anytime and anywhere; You can also use the app for color matching and color editing functions. The WS-422 model supports caliber switching to meet the measurement of samples of different sizes.
1、 Instrument characteristics
1. The more caliber you have, the more you can measure
Two caliber/small caliber/large caliber
2. Automatic calibration, take care of yourself
3 SCI/SCE
Can remove gloss measurement, more consistent with human perception
4. Multiple measurement parameters
30+measurement indicators including covering power, whiteness, yellowing, etc
5. Multiple lighting conditions
26 evaluation indicators for light sources
6. Good repeatability and stable measurement -0.06
7. Ensure passing metrological certification
8. Portable massive color card database
Connect to the mobile app, create a color database, and input color card information such as printing, coatings, textiles, etc. No need to carry heavy color cards, you can use the instrument to search for similar colors in multiple sets of color cards anytime and anywhere
9. Cloud based database for easier viewing and uploading
Provide an official color chart database for easy searching and use. The color information library created by users 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 library and color formulas in the cloud. Through a unique invitation code, the information library and color formulas can be shared with merchants and users for use
10. Better performance
UV - visible fluorescence
Camera - visible measurement area
Paint color matching software - can use the app's color correction function
