Obtain spatial average PAR readings for light quantity measurement

The 6-sensor handheld bar on this Quantum Light Meter provides a spatial averaged PAR (Photosynthetically Active Radiation) reading. PAR averages are a more comprehensive indicator of light quantity reaching your plants, and serve as a powerful tool to manage lighting.

Meter approximates radiation between 400 and 700 nanometers ( PAR ) as umol m-2s-1.
