PAR Sensor
Photosynthetically Active Radiation sensors

Detect radiation in the 400-700 nm waveband with standard and scalar LI-COR® PAR sensors configured for YSI 6-Series sondes.

PAR irradiance includes in vivo absorption bandwidths of:
-chlorophyll a, b, and c,
-the pigments contained within the cytoplasm of blue-green algae (cyanobacteria), and
-the chloroplasts of plants (including phytoplankton) that capture light energy for photosynthesis.

These sensors are available for use on the following sondes:

  • 6600 V2-2
  • 6600EDS V2

Wiping systems for sensors are available.
