Chlorophyll Concentration
Linear OutputThe Apogee chlorophyll concentration meter is calibrated to measure chlorophyll concentration in leaves with units of mol of chlorophyll per m2. This eliminates the problems with relative indexes of chlorophyll concentration.For reference and comparison purposes, the Apogee meter also outputs relative units [CCI or SPAD] if desired.For details see: Parry, C., Blonquist Jr., J.M., & Bugbee, B. 2014. In situ measurement of leaf chlorophyll concentration: analysis of the optical/absolute relationship. Plant, Cell and Environment 37:2508-2502.

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.

YODA Profiler
The YODA profiler (“Yoing” Ocean Data Acquisition Profiler) is a “tow-yo” instrument to profile the water column with high spatial resolution from small boats without occupying much space. The instrument is provided with a deployment winch and sensors measuring conductivity, temperature, pressure, chlorophyll, turbidity and dissolved oxygen. The brush at the top of the instrument allows for a stabilizing effect on the free-fall sinking speed, which is approximately constant at 0.2 m/s. All data are stored internally and downloaded into a PC through a wet-connector and interface.
