PAR Photosynthetically Active Radiation Sensor



M1-PAR (PAR Photosynthetically Active Radiation Sensor)  measures light in the spectral region between 400 and 700 nm. This particular radiation is called photosynthetic radiation.

Calibration performed with halogen lamp with known light output.

The probe is designed to direct all the light hitting its surface to the sensible part.

Equipped with a spirit level.
