The compact ML-020P PAR sensor or Quantum sensor has a special opical filter to mimic the spectral response function of typical plant leaves. The PAR sensor is most common to be used in horticulture or agriculture aplications. The photon active range between 400 to 700 nm represents the Photosynthetically Active Radiation (PAR) known as Photosynthetic Photon Flux (PPF) or Photosynthetic Photon Flux Density (PPFD) in μmol/m/s (micromoles of photons per meters squared per second).
The low output Voltage of the sensor can be easily converted to a 4-20mA current or higher Voltage using the MS-4..20mA converter. The mV/mA converter can be pre-programmed and optimized within the operating range compatible with common measurement equipment.
