  • Wireless Gas Detection Sensor
    Publication number: 20190035253
    Abstract: A gas sensing device (10) (100) and method are provided. The battery-powered wireless gas sensing device (10) (100) has low power consumption components and power-saving functions. The gas sensing device (10) (100) has extended battery life and run times so as not to require battery replacement or recharging prior to expiration of the standard gas sensor calibration cycle.

  • Polarographic PPB oxygen gas sensor
    Patent number: 5393392
    Abstract: A polarographic electrochemical cell for the measurement of oxygen in ppb. The cathode in the system is a non-depleting carbon polytetrafluoroethylene electrode catalytically specific for oxygen reduction. The anode is a composite nickel matrix. The reaction at the anode is an electrochemical oxidation reaction but there are no soluble byproducts that contaminate the electrode. The reaction at the anode is a simple oxidation, state-of-change of the nickel in the nickel composite matrix.

  • Micro fuel-cell oxygen gas sensor
    Patent number: 5334295
    Abstract: An oxygen sensor for measuring oxygen in the ppb range. The sensor comprises an electrochemical cell. The oxygen is metered to the cathode based on gaseous phase diffusion to provide a measurement proportional to volumetric concentration. Hydrogen is metered to the anode in an amount in excess of the oxygen being reduced at the cathode. A current is generated which is linear to the volumetric concentration of the oxygen in the sample gas. The concentration of the oxygen is measured based on the current generated.
