ETF136Reflectivity measuring instrumentspecialPoint: The instrument is a special equipment for measuring the reflectivity of motor vehicle rearview mirror (or mirror). The instrument is composed of intelligent measuring instrument, optical integrating sphere, parallel light pipe, standard light source and so on. The instrument adopts the structure of standard modular design, the use of single-chip digital as the central processing unit of luminous flux signal by analog-to-digital conversion by CPU after the calculation, compensation, real-time display the reflectivity of the device under test. The instrument uses a simple, intuitive and accurate readings, facilitates the detection and control of the production site and laboratory quality, this product has the convenience of calibration, meet the needs of different occasions, suitable for all kinds of surface and non specular reflectance measurement. Application scope1, automobile, motorcycle rearview mirror reflectivity measurement 2, other mirror or non specular object surface reflectance measurement Main technical parameters:Model ETF-136 measuring range0~100% measurement accuracyBetter than 2%; RepeatabilityBetter than 2%; working voltageAC220/50Hz; Ambient humidity No less than 85%.
