the instrument measuring brightness, opacity and color by diffused reflectance according to relevant iso standards. Incorporated the best features which can be seen on international class of spectros. With highly advanced holographic diffraction grating for dispersing diffused light, coupled with a highly sensitive and accurate discrete sensing photo diode array detector. Easy to use window based software to measure diffused brightness, (iso, tappi), color values, cie tri stimulus, rx, ry, rz, x, y, z, l, a, b, l*c*h* values, yellowness, whiteness, color graph, spectral reflectivity 400-700 nm and color difference using cie lab, hunter, suitable for pulp, paper, paperboard, textile, dies and pigments, paints, plastics, ceramics, cosmetics, pharmaceuticals, leather, mineral, color filters and packing industries according to international standards. Made with imported optics imported sensors. With pentium computer, color monitor and printer.
