Spectrometer
LI-180
Plant growth and reproduction are driven by photosynthetically active radiation (PAR), defined as wavelengths between 400 and 700 nanometers. This interval is often separated into three distinct “color” bands for plant research. Modifying the intensity of red, blue, green wavelengths, along with additional near-UV (380-400 nm) and far-red (700-780 nm) bands, can influence a variety of plant characteristics, such as growth rate, chemical composition, and more.

Underwater Quantum Sensor
LI-192
The LI-192 Underwater Quantum Sensor measures PAR from all angles in one hemisphere. The LI-192 works in air or underwater at depths up to 560 meters. The measurements are cosine corrected and typically expressed as Photosynthetic Photon Flux Density (PPFD). For simultaneous measurements of downwelling and upwelling PAR, two sensors can be mounted on the 2009S Lowering Frame.

Water quality profiler with optical fast DO sensor
AAQ-RINKO
The water quality profiler, AAQ 1183 has been redesigned as AAQ-RINKO with an optical fast response (63% response in water, 0.4 s) DO sensor, RINKO. Conventional water quality profilers with a slow response DO sensor require holding the instrument for a certain period at the measurement depths. AAQ-RINKO makes vertical measurements possible with a profiling speed of 0.5 m/s, similar to CTD observation, thereby significantly reducing the observation time. In addition to conductivity, temperature, depth, chlorophyll, turbidity, DO and pH, AAQ-RINKO also enables simultaneous installation of PAR (Photosynthetic Available Radiation) and ORP (Oxidation Reduction Potential) sensors. The processing unit is available in three types in accordance with the observation applications.

Underwater Quantum/PAR Sensors
Photosynthetic radiation is essential for the growth of the photosynthetic organisms such as corals. The wavelength range from 400 to 700 nm is PAR (Photosynthetically Active Radiation) or PPFD (Photosynthetic Photon Flux Density). Apogee quantum/PAR sensors are calibrated to measure the number of photons of light across this range.
