The working principle and usage of Bai Duyi -qinsun

The whiteness instrument is widely used in papermaking, coatings, plastic products, white cement, talc powder, starch, flour, cosmetics and other substances. The detection method is not cumbersome. Let me introduce it in detail below.

1. The principle of the working principle of Bai Duyi

Black Duzi uses the integral ball to achieve the measurement of the spectrum phenomenon. The light, through the light mirror and color filter into the purple light of the orchid, enter the integral ball, the light is reflected on the inner wall of the integral ball, and the light is illuminated on the sample of the test port. After the group, the silicon light battery was received and converted into a electrical signal. Another base signal of the silicon light battery received. The two telecommunications signals are enlarged, mixed, determined by digital display, and a built -in printer printing.

2. How to use the white duct

1. Connect the power supply switch behind the instrument. Put the black cylinder on the measurement empty and use the instrument to adjust the zero potential level. After the instrument is zero, after the instrument is zero -position stable, remove the black tube, and put the standard white panel with the standard whiteness device to adjust the standard whiteness value.

2. After the instrument is calibrated, remove the standard whiteness board to measure the samples required to be measured to obtain the required whiteness value.
