This Colorimeter is a very portable and easy-to-use tri-stimulus Colorimeter, specially designed for measuring the color difference between two colors.
AC-115S Colorimeter is used to measure non-luminous and non-fluorescent samples, such as textiles, paper, leather, spray materials and others. It is a useful tool in quality control and a wide range of industrial applications.
When measuring, the measuring head of this watch should be closely attached to the color sample to be tested without any gap.
Color difference shows ∆(L*,a*,b*), ∆(E*ab,C*ab,H*ab), ∆ ( Y , x , y ) , ∆ ( X , Y , Z ) , ∆ ( Rs ,Gs ,Bs) or ∆(WI,YI,Tw).
Color space display ( L* , a* ,b* ), ( L* ,C* ab, hab), (Y,x,y), (X,Y,Z), (Rs,Gs,Bs) or ( WI, YI, Tw).
Statistical functions (maximum, minimum, average and standard deviation).
Configurable color difference allows error judgment PASS/WARN/FAIL.
9 target colors can be stored.
User calibration function ensures high accuracy.
Automatic memory (99 groups) and read function.
Digital backlight display, no parallax.
Auto power off function.
Using the optional USB cable and its software, it can communicate with a PC computer to realize functions such as data collection, processing, analysis and printing.
