ROKTOOLS Color Difference Meter With 8mm Test Aperture Portable Colorimeter

         Colorimetry is the measurement of the wavelength and the intensity of electromagnetic radiation in the visible region of the spectrum. Colorimetry can help find the concentration of substances, since the amount and colour of the light that is absorbed or transmitted depends on properties of the solution, including the concentration of particles in it. A colorimeter is an instrument that compares the amount of light getting through a solution with the amount that can get through a sample of pure solvent. A colorimeter contains a photocell is able to detect the amount of light which passes through the solution under investigation. The more light that hits the photocell, the higher the current it produces, hence showing the absorbance of light.

       CDME-1132  colorimeter is a high precision, high stability, versatile colorimeter. It has eight kinds of measuring light source (A, D50, D65, C, F2, F7, F11 and F12); six kinds of color modes (CIE1976LAB, CIEXYZ, CIELUV, HunterLAB, sRGB, white yellowness); eight kinds of color difference formula (Delta E * ab, Delta ECMC, Delta EISO, Delta ECIE94, Delta EFCM Ⅱ, Delta ELuv, Delta Ehunter, Delta EsRGB); three languages patterns (Simplified Chinese, Traditional Chinese and English), and three measurements caliber choice for users. The  Color Difference Meter can be whiteness and yellowness measurements and average measurements, with large-capacity data storage space, you also can add mini-printers to do real-time printing measurement data. It can be used with standard "color analysis system" software. Caliber 8mm version is a general-purpose color difference meter, considering the general method for detecting color, all walks of life habit, and the measuring caliber requirements of various materials. 8mm caliber version provides great convenience and trustworthy reliability for all industry to discuss the color technology, because of its versatility, its tiny table difference, and stability.
