Features: Six colour spaces for measurement and comparison : (L*,a*,b*), L*, C*ab, hab), (Y, x, y), (X, Y, Z), (Rs, Gs, Bs) or (WI, YI, Tw). Statistics of max, min, avg and standard deviation displayed. Colour difference tolerance can be set for PASS/WARN/FAIL tests. 9 different colour targets can be stored for comparison. User calibration function. Data storage and recall. Low battery indication and auto power off. Measuring geometry: - 45° / 0° ; Illumination at 45°, measurement at 0° Colour space measurement: - (L*,a*,b*), (L*, C*ab, hab), (Y, x, y), (X, Y, Z), (Rs, Gs, Bs) or (WI, YI, Tw). Colour difference measurement: - ∆(L*, a*, b*), ∆(E*ab, C*ab, H*ab), ∆(Y, x, y), ∆(X,Y,Z), ∆(Rs, Gs, Bs) or ∆(WI, YI, Tw) Illuminant: - White LED lamp Measuring area: - approx. ø 10 mm Measuring range ; - L* : 5 to 100 Target colour memory: - 9 values, can be set by measurement or manually entered values Measurement conditions: - Observe : CIE 2° standard observer Repeatability: - Standard deviation within ∆E*ab 0.5 (measurement conditions: avg of measurements of standard white plate) Min. interval between measurements: - approx. 2 seconds Applications: This instrument can be used to measure the colour of no lighting and non-fluorescent samples such as textile, paper, leathers, painting materials, etc. It can also be used for calculating colour differences between two colour in any of the six colour spaces. It is a useful tool for quality control and wide industrial applications. Measuring Principle: Colour meter works according to the tristimulus absorption and imitates human vision. It does this by means of 3 colour sensors with almost identical spectral sensitivity in the areas of red, green and blue. The colour values determined in this way are represented as X, Y and Z values on the display and automatically converted to other colour spaces
