  An online calibration system for an electrochemical sensor. The calibration system comprises a calibration electrode coupled with a redox species, where the redox species is configured to control a pH of a reference solution local to the calibration electrode, such that when a voltammetric signal is applied to the calibration electrode the output generated from the calibration system is determined by the local environment pH. The output signal from the calibration system is used to calibrate a reference potential generated by a reference system of the electrochemical sensor to correct for drift in the reference potential when the electrochemical sensor is being used. The calibration electrode may be disposed in a reference cell of the electrochemical sensor.

  一种用于电化学传感器的在线校准系统。校准系统包括一个与氧化还原物质耦合的校准电极，其中氧化还原物质被配置为控制校准电极本地参考溶液的 pH 值，从而当伏安信号施加到校准电极时，校准系统产生的输出由本地环境 pH 值决定。校准系统的输出信号用于校准电化学传感器的参比系统产生的参比电位，以纠正电化学传感器使用时参比电位的漂移。校准电极可安装在电化学传感器的基准池中。

  A reference system for an electrochemical or ion selective sensor where a reference electrode is coupled with a redox active species and the redox active species is configured to set a pH value of a local environment of a low buffer/low buffering capacity analyte media proximal to the reference electrode. The pH value of the low buffer/low buffering capacity proximal to the reference electrode may be controlled to a pH value at least one pH unit above or below pH 7. The voltammetric response of the redox active species is used as a reference and/or reference signal for the electrochemical or ion selective sensor.
