HI-7041L Electrolyte Solution for Polarographic Sensors, 500ml

Potassium chloride electrolyte solution

The HI 7041 electrolyte solution is suitable to maintain Polargraphic DO probes and is ready to use in 500mL and 30mL bottles. An oxygen probe is composed of a platinum electrode and a solid silver electrode. The HI-7041L 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.
