Automatic Whiteness Meter For Measuring the Whiteness Of Paper,Powder

Automatic whiteness meter is widely used for measuring the whiteness measurement of objects or powders with flat non color surface, and can accurately obtain the whiteness value consistent with the visual sensitivity. For the object treated with fluorescent brightener, it can be display quantitatively the whiteness value after fluorescent brightening,and also for measuring accurately the opacity of paper. It can be widely used in whiteness measurement of textile printing and dyeing, paint, chemical building materials, paper and paperboard, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.

Description

WSB-2A is a fully automatic whiteness meter,which can be widely used in whiteness measurement of object without be affected by the measurement direction of the sample. With microcomputer configuration, average measurement mode, time display of month, month and day, data storage and query, full-automatic proofreading and RS232 interface design,you can fast and high accuracy get the whiteness measurement result.
