Dissolved Oxygen Sensor
Catalog NO.: AIMRSE-LAB-SEN-036 Manufacturer PN: LAB-DO-SEN
• Facilitates system integration. Self-maintainable. Small size, high precision, fast response, low power consumption.
Measures dissolved oxygen parameters in water bodies.
The dissolved oxygen sensor employs polarographic principles, measuring oxygen concentration through current flow between an anode and cathode. Internal electrolyte and a gas-permeable membrane generate current between electrodes. The electrolyte reacts exclusively with oxygen, preventing external polarization interference. Constant negative cathode polarization maintains measurement accuracy at 97% or higher relative to true values.
