Abstract：In order to optimize coal blending process and improve test precision of vitrinite reflectance,taking MSP UV-VI2000 photometer as research object,introduced its working principle,process. Obtained the general formal and special formula of vitrinite reflectance. The comparison of the two formulas show that,the special formula needs to correct equipment and the process is complicated.The special formu-la has an universally applicable characteristic. The experimental procedure includes measuring,drawing curve,calculating reflectance and drawing histogram.Based on the formula,analyze the maximum measurement range and resolving power of photometer.Compare two working curves which have different slope.Provide principles with which should be complied when measuring the reflectance with photometer.
