LI-190 Quantum Sensor

LI-190 Quantum Sensor This sensor has a response between 400 and 700 nm and fits the ideal quantum response closely. These are the wavelengths that drive photosynthesis (PAR-Photosynthetically Active Radiation). Integration of PAR closely approximates the potential for photosynthetic activity. These sensors are popular for studies of plant growth both in native environments and in greenhouses. They are not affected by the disproportionate amounts of infrared or yellow that can distort the results of plant growth studies based on pyranometers or photometers.
