Nine whiteness indexes such as R457 / iso2470 blue light whiteness were measured
WSB-0/1/2 whiteness meter is a new lightweight portable instrument specially launched by China CHNSpec to measure whiteness value. It can measure 9 whiteness indexes such as R457/iso2470 blue whiteness. The instrument has the functions of automatic calibration, one-second output result, comparing whiteness color difference, etc. It can also be connected with cell phone APP and WeChat app, which is more convenient to use.
9 whiteness indexes:(ASTM,CIE,Ganz,Hunter,Tauble, Berger,AATCC,R457/IOS2470,GB/T17644)
It has excellent consistency with other competitive products in the United States, Japan and Europe
With higher brightness value, dirt resistance, wear resistance and discoloration resistance, advanced ceramic whiteboard ensure the accuracy of automatic calibration and one key measurement
4mm test caliber to meet more sample sizes
It also supports connecting mobile app and wechat applet
Output measurement data in seconds
App / applet mass data storage
