Photosynthetically Active Radiation Probe
LPPAR01 - Delta OHM S.r.L.
The LPPAR01 probe measures the ratio between the number of photons that strike a surfacein one second, in the 400 nm…700 nm spectral range and the surface area (m2). This quantity is defined as PAR: Photosynthetically Active Radiation.
