Product Description
This instrument designed according to the luminousity measurement of d/o international standard is applicable to measurement of optical features such as whiteness, transparency, opacity, scattering coefficient and absorbing efficient.
The instrument adopts the technique of a microcomputor and a black barrel and a standard whiteness plate. Therefore, it can be adjusted to a zero automatically and can calibrate the accuracy of "numerical value" with its data never lost because of power cut-off and instrument switching-off. In addition, it can automatically memorize measured data or can automatically computer in accordance with specified formulas. So the instrument is excellent in performance. High in measuring accuracy and is concenient in operation.
