Claims34
A chlorine sensor comprising a gold cathode and a platinum anode, the platinum anode being sealed inside a low electrical resistance, water-permeable membrane comprising a tube having a wall thickness of at least 0.004 inches, wherein the tube provides a barrier for the platinum anode to both oxygen and anions, and wherein the tube comprises a copolymer of tetrafluoroethylene.
A halogen sensor comprising a metal anode, the metal anode being sealed inside a low electrical resistance, water-permeable membrane comprising a tube having a wall thickness of at least 0.004 inches, wherein the tube provides a barrier for the metal anode to both oxygen and anions, and wherein the tube comprises a copolymer of tetrafluoroethylene, and a metal cathode.
A method of making a halogen sensor comprising the steps of:
- providing a metal anode,
- providing a low electrical resistance, water-permeable tube comprising a copolymer of tetrafluoroethylene having a low electrical resistance, having water-permeability, and having a wall thickness of at least 0.004 inches, and
- sealing the metal anode inside the tube so that the tube provides a barrier for the metal anode to both oxygen and anions.
