portable whiteness meter - SBDY-2

°cThis instrument brightness value is R457 blue whiteness.it can be used measuring the whiteness value of white materials and close white surfaces.

it based on the principle of photoelectric effect and D65 light source(R457) to measuring the whiteness value of powder,board,paper,paste,sheet substances.the application range are as follows.

Application:

1.Chemical and building materials industry:white cement(powder),paint(pasty),coating(pasty),plastic(boards),steel plate(boards),ceramics(powder),gypsum(powder),wallpaper(paper/sheet),porcelain enamel(powder),calcium carbonate.etc.

2.cosmetic industry:tooth paste,face cream,etc.

3.food industry:flour(powder),starch(powder),salt(powder),sugar(powder),fish balls(paste),etc.

4.paper making industry:paper factory,printing factory,publishing company,etc.

5.textile industry:fabric,weaving factory,cotton,etc.

Characteristics:

1.LED display window,A/D shift,data process.

2.high efficiency,low consumption and superior reliability.

3.advanced components makes it running stable and reliability.

4.simple optical path design makes it easy to operation and maintenance.

5.modified filter system can be quantative reflected the fluorescent whitening value.

6.With low voltage warning function can remind the user to change battery timely. it is good for ensuring the measure result accuracy and effective.

7.it can be accurately measure the opacity of papers.
