ZWL-9107 horizontal distribution photometer is developed by HANGZHOU ZHONGWEI PHOTOELECTRICITY Co., Ltd in China. Advanced technology and steady servo transmission structure, matched with our testing instrument, it makes the system faster and more accurate. The basic structure contains two groups of high precision worm 360 degree\+180 degree rotating platform and fixture. The operator puts the tested lamp into the fixture and through rotating the lamp; It will finish the spacial photometric distribution test. With the method of C-γ Testing, it matches with the testing criterion of road light, as well as indoor lighting.
