Portable spectrophotometer CS-520 is with the powerful performance configuration which makes color measurement more professional. Excellent inter-instrument agreement ensures consistency of the measurement data of multiple devices; Wireless connection with Android or IOS devices via Bluetooth. It greatly expands the application boundary of color spectrophotometer; automatic calibration, magnetic seat charging, touch screen operation, switchable apertures, UV included / excluded... it will fully upgrade the user experience. Part 1. Product Features 1. 20 kinds of color indexes and 26 kinds of illuminants Spectrophotometer CS-520 supports 26 kinds of illuminants such as D65/D50,etc. It can get the value of reflectance, CIE-Lab, CIE-LCh, whiteness, yellowness, opacity, color strength and other color indexes. 2. Excellent inter-instrument Agreement inter-instrument agreement ＜0.2 which ensures test results consistency of multiple devices. 3. Auto calibration The revolutionary auto calibration technology allows the instrument to achieve automatic calibration, which greatly improves the user experience. 4. Switchable Apertures 11mm/6mm/1*3mm Durable and stable aperture size to measure samples with different sizes 5. UV Included/ UV Excluded UV Included/ UV Excluded to measure color and color difference for samples with fluorescence 6. Multi-function calibration base The multi-function calibration base keeps the white tile being protected, combining calibration and charging functions in one. When instrument is placed on the base, it will be automatically charged and calibrated. It saves a lot of time for the user to charge and calibration the device. 7. Connect to the mobile device App to expand more functions Connect to APP to find the similar color from different color swatches. Personal color database can also be established in the cloud and samples saved in cloud can be set into target for color difference test. From APP, we can also obtain instrument data or download data to the instrument. 8. Camera to see the measurement area Integrated camera to see the measurement area for accurate test Part 2.
