Description:
The BGT-PAR1(L) solar radiation sensor can be used to measure the photosynthetic effective radiation of natural light within the wavelength range of 400-700nm and it is simple and cost-effective, can be used all the day, can be reversed or tilted. It is widely used in plant growth, heat conversion box and solar energy monitoring of soil moisture evapotranspiration loss.
