Feature:

1. It is based on the principle that a photosensitive element converts ultraviolet light into a measurable electrical signal, realize online monitoring of ultraviolet light.
2. The measurement data is more comprehensive. The product outputs 485 signals, can communicate at a distance of 2000 meters, and supports secondary development.
3. With wall‑mounted waterproof shell, high protection level, can be used in outdoor rain and snow environment for a long time.
4. It can measure highly sensitive ultraviolet rays from 290-390nm and accurately measure the intensity of ultraviolet rays.
5. It is widely used in environmental, meteorological, agricultural and forestry testing. Measure ultraviolet rays in the air and under artificial light sources.
