OCEAN SEVEN 306 pH & redox sensor
Up to 700 bar, Analog output, easy CTD integration
The OCEAN SEVEN 306 pH and redox sensor is provided with analogue output 0..5V and allows the in situ determination of pH and optionally redox (ORP - Oxidation Reduction Potential) in natural waters as oceans, lakes, rivers and estuaries, at depths down to 700 bar. The OCEAN SEVEN 306 pH and redox combined probe, is specifically designed to simplify the integration in CTD probe or third-part instruments.
