Aperture Handheld Colorimeter for Accurate Color Measurement GAOTek

Description Overview GAOTek aperture handheld colorimeter uses the principle of combination LED precision spectroscopy, separates the light according to a certain wavelength interval, and adopts groups of sensor array to perform sensitive analysis. It is very sensitive to any colors. It not only can measure L x ab value and delta E value accurately, but also can display spectral reflectance curve which can realize color matching function and calculate the real parameters of various color formulas.   Features Aesthetic design perfectly combined with ergonomics structure 45 or 0 geometrical optics structure 5 in (8.8 cm) large capacitive touch screen Two standard observer perspectives Multiple light sources modes Variety of color systems The repeatability E x ab is within 0.04% The errors between each instrument E x ab are less than 0.2 Large capacity storage, can save more than 10000 data PC software with powerful extension functions High hardware configuration with a number of innovative technologies Oversized integrating sphere 15 ° oblique angle screen, more in line with the human eye observation.
