Digital Photo Meters Color Meter Features This meter is designed to measure colors of non-fluorescent samples such as fibers, paper, leather, paints, and more for quality control and a wide range of industrial applications. Color differences (LxWx, a*, b*), (E*ab, C*ab, H*ab), (Y, x, y), (X, Y), (Rs, Gs, Bs) or (WI, YI, Tw)* Color Space Displayed a*, b*. ), (LC, C*ab, hab), (Y, x, y), (X, Y, Z), (Rs, Gs, Bs) or (WI, YI, Tw)* Statistical functions (Max, Min, Average, Standard Deviation) Set color tolerance to perform PASS/WARN/FAIL. Memory 9 colors of color differentiation * User calibration function ensures greater accuracy Auto Memory (99 colors. Set) & Lead Function * Digital backlight display* Auto power off function* USB and data output; Uses USB data output for connecting to PC; Screen Triple 4-digit LCD display; Auto power-off approx. 3 minute data memory capacity 99 sets (directly read from LCD display); Display geometry lighting/ display 45/0: 45 in lighting (measured area color difference: L,a*,b*), (E*ab,C*). ab, H*ab. ), (Y,x,y), (X,Y,Z), (Rs,Gs,Bs) or (WI, YI, Tw) Color Space: (L, a*, b*), (L, C*ab, hab), (Y, x, y), (X, Y, Z), (Rs, Gs, Bs) or (Wide, Y), target color memory 9 channels measured or keypad from L*:5~ 100 measurement conditions Observations: CIE 2 Standard Observator: Light White LED Lamp Reproductivity: Standard deviation within E*ab 0.5 (Measurement condition: average of measurement of standard white panel) Minimum interval between measurement approx 2 seconds operating temperature and humidity<; 85% RH storage temperature and humidity<; 70% RH power 4x1.5 AAA (UM-4) Battery dimensions 14) 14) mm (5.5 mm) x 2.9 x 1.4 inches) Weight (without batteries): Approx. 7.8 oz (220 g) Standard Accessories: Body measuring head White calibration card carrying case (B04) USB data cable with manual optional accessories software
