LEADMED
>> Information
Dissolved oxygen sensor is based on the fluorescence quenching principle. The concentration of oxygen molecule can be calculated by measuring the phase difference between excitation light and reference light and comparing with the internal calibration value. It is suitable for surface water, groundwater, industrial water, waste water and other application.
>> Characteristics
Low maintenance cost, no need to replace the diaphragm and electrolyte;
RS485 output, standard Mod-bus protocol;
No oxygen consumption, no flow speed limited;
Automatic temperature compensation, good stability;
Optical measurement, fast response;
No pollution, environmental protection detection.
