Apogee Red – Far-Red Sensors

Measuring light in the Red – Far-red range of 645nm to 665nm (red) and 720nm to 740nm (far-red), the Apogee Red – Far-red sensors measure the ratio of Red – Far-red which influences plant height, leaf expansion rates and other responses to light.

The sensor is available in analogue, SDI-12 or Modbus outputs.

• S2-131-SS: Red – Far-red Sensor, Analog mV output.
• S2-431-SS: Red – Far-red Sensor, SDI-12 output.
• S2-432-SS: Red – Far-red Sensor, Modbus output.
