ETF-136 reflectance meter is a measuring instrument that special motor vehicle mirror device (or similar products) reflectivity. Instrument consists of intelligent measurement instruments, light integrating sphere , parallel light tubes, and other components constitute the standard light , easy to operate, can be quickly and accurately achieve reflectivity measurements. Structure using a standardized instrument modular design , using the latest digital microcontroller as a central processing unit , its luminous flux measured by the CPU to calculate the compensated signal by the analog-digital conversion , the reflectance can be measured in real time display device. The instrument is simple and quick to use , intuitive readings, accurate , easy to produce on-site and laboratory testing and quality control , this product has convenient calibration methods to meet the needs of different occasions , for all types of specular and non- specular reflectivity measurements.
