The water quality profiler has been redesigned as with an optical fast response (63% response in water, 0.4 s) DO sensor. Conventional water quality profilers with a slow response DO sensor require holding the instrument for a certain period at the measurement depths. It makes vertical measurements possible with a profiling speed of 0.5 m/s, similar to CTD observation, thereby significantly reducing the observation time. Parameters measured .
& also simultaneous installation of PAR (Photosynthetic Available Radiation) & ORP (Oxidation Reduction Potential) sensors. Different interface units are available in accordance with the observation applications.
