The LI-193 Underwater Spherical Quantum Sensor gives an added dimension to underwater PAR measurements as it measures photon flux from all directions. This measurement is referred to as Photosynthetic Photon Flux Fluence Rate (PPFFR) or Quantum Scalar Irradiance. This is important, for example, when studying phytoplankton, which utilize radiation from all directions for photosynthesis.
The LI-193 features a high sensitivity optical design and compact, rugged construction (3400 kPa, 350 meters depth, 3400 kPa = 493 psi).
