Electrolyte Solution for Polarographic DO Probes

Electrolyte Solution for Polarographic DO Probes

The HI-7041 electrolyte solution is suitable to maintain Polarographic Dissolved Oxygen probes and is ready to use in 30mL bottles. An oxygen probe is composed of a platinum electrode and a solid silver electrode. The HI-7041S is a concentrated Potassium Chloride solution held in place over the electrode by a PTFE (Polytetrafluoroethylene) membrane. With polarographic technology, an external voltage is applied to the platinum cathode, silver anode, electrolyte solution and gas-permeable membrane to establish a current that is proportional to the concentration of oxygen in a solution.
