Description
Overview
GAOTek solar radiation measuring sensor meter is produced based thermopile principle, sensing elements are made by winding – plated thermopiles with Mult contacts. Its surface is coated by black coating with high absorption rate. Hot contacts on the sensors surface, while the cold junction is located within the body, temperature difference between the hot and cold junction generates electromotive force, the thermoelectric effect is proportional to the solar radiation.
Features
- Conform to the WMO standard
- Suitable for harsh environment
- With horizontal bubble
- High sensitivity
- Double transmission glass
- Easy installation
