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.

Automatic calibration

R457 / iso2470 blue light whiteness and other 9 whiteness indexes

One key measurement, 1.5s results

Contrast whiteness color difference

Connect mobile app and wechat applet

Mass data storage

Nine whiteness indexes such as R457 / iso2470 blue light whiteness were measured

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

 

Automatic calibration

With higher brightness value, dirt resistance, wear resistance and discoloration resistance, advanced ceramic whiteboard ensure the accuracy of automatic calibration and one key measurement

 

360 degree function improvement

4mm test caliber to meet more sample sizes

It also supports connecting mobile app and wechat applet

Output measurement data in seconds
