    • A chronoamperometric method and device to determine concentration of an electrochemically active species in a fluid and pH of the fluid. A plurality of sets of calibration relationships may be determined for a sensor in an aqueous solution, the sensor having one or more working electrodes and one or more reference electrodes. A first plurality of potentials may be applied across the working and reference electrodes of the sensor in solution, and a first plurality of currents and current differences obtained as a function of the applied first plurality of potentials. Concentration of an electrochemically active species may then be determined as a function of the obtained first plurality of currents and current differences using the plural sets of calibration relationships, and pH of the solution may be determined as a function of the obtained first plurality of currents and current differences using the plural sets of calibration relationships.
    • 用于确定流体中电化学活性物质的浓度和流体pH的计时电流法和装置。 可以为水溶液中的传感器确定多组校准关系,该传感器具有一个或多个工作电极和一个或多个参考电极。 第一多个电位可以施加在溶液中的传感器的工作参考电极和参考电极之间,并且作为所施加的第一多个电位的函数获得的第一多个电流和电流差。 然后可以使用多组校准关系来确定电化学活性物质的浓度作为获得的第一多个电流和电流差异的函数,并且溶液的pH可以被确定为所获得的第一多个电流的函数,并且 使用多组校准关系的电流差异。
