Features:
1. The hand held PAR meter mainly used for agriculture, forestry and other research and production departments for PAR radiation measurement.
2. It is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700 nanometer.
Its characteristics are the spectral response simulation probe photosynthetic function effectively, digital show, portable compact,with good accuracy and stability.
3. In controlled environment agriculture (CEA), it is for growers to measure light to avoid the risk of wasting energy or damaging their plants.
