Designed for horticulture and agricultural applications, the photon active range of the compactML-020P PAR (MTI.AWS.EK.020P) Sensor or Quantum sensor is between 400 to 700 nm; that is the Photosynthetically Active Radiation (PAR), otherwise known as Photosynthetic Photon Flux (PPF), or Photosynthetic Photon Flux Density (PPFD), represented as μmol/m/s (micromoles of photons per meters squared per second). The low output Voltage of the sensor can easily be converted to a 4-20mA current or higher Voltage using the MS-4.20mA converter. The mV/mA converter can be pre-programmed and optimised within the operating range compatible with standard measurement equipment.
