PAR photosynthetic radiation meter
Photosynthetic radiation meter M1-PAR measures the number of photons, in the rang from 400 to 700 nm, that arrive in one second on a given surface, this measurement is called Photosynthetically Active Radiation.
Calibration performed with a halogen lamp whose spectral irradiance in area of interest is known.
Probe constructed in such a way as to direct all incident rays onto the sensitive part of the instrument, regardless of direction (according to the Law of Cosines).
Supplied with a support ring equipped with a spherical bubble.
