The UVB detector of the Gian Garden brand focuses on measuring the radiation intensity of UVB (ultraviolet B band) and has rich practical functions. After two years of research and development as well as debugging, it can accurately measure UVB values, and its accuracy reaches the same level as that of mainstream imported detection instruments. It is very useful whether for outdoor monitoring or for controlling the light in the rearing environment of reptile pets. It can record 9 segments of detection data, facilitating the query and tracking of the status changes of UVB lamps. Moreover, it has a reversible probe design, which solves the problem of ground data collection, greatly increasing the detection flexibility and helping to accurately grasp the all-round light-receiving data of reptile pets. It fully meets the light monitoring needs in reptile pet rearing and can also be easily adapted to outdoor scenarios.
