    摘要： A compact multiparameter instrument for electrochemical measurements is described. The instrument facilitates rapid engagement and disengagement of a variety of sensor elements in such a manner as to prevent accidental mismatch of sensor elements and sensor input ports. Positive identification of specific sensors is ensured by including color marking or other indicia on the sensor connectors that are matched to corresponding markings on the meter body. Measurements of specific parameters such as temperature may readily be shared among all other sensors connected to the instrument. A method of rapidly reconfiguring the instrument to provide extended or different capabilities is described.

    摘要： The present invention comprises an electrochemical metering apparatus that provides for convenient storage and presentation of the analytical electrode, simple assembly, and two calibration modes. The apparatus includes an electrode storage and presentation assembly that permits the user to introduce the electrode into a sample solution while simultaneously observing the meter's output, and store the electrode when not in use. All structural components are intended to fit together with interlocking tabs and windows. A serial port fits within the construction of the main housing without the need for bolts, and battery clips that depend directly from the circuit board obviate the need for wiring connections. The present invention also features two calibration modes. A "segment addition" mode permits separation of the voltage/concentration curve into individually plotted regions, the number of which depends on the number of reference solutions used in the calibration procedure. The segment corresponding most closely to the measured potential of a sample solution is used to calculate concentration. In an alternative calibration mode, one or more reference solutions are used to establish metered voltage/concentration combinations that are compared with expected, known values. Any discrepancies therebetween furnish a "noise level" value associated with the apparatus that can be used to more precisely define the orientation of the voltage/concentration curve.

    摘要翻译： 本发明包括电化学计量装置，其提供方便的分析电极的存储和呈现，简单的组装和两种校准模式。 该装置包括电极存储和呈现组件，其允许用户将电极引入样品溶液中同时观察仪表的输出，并且在不使用时存储电极。 所有的结构部件都是用联锁片和窗户配合在一起的。 串行端口适合主外壳的结构，而不需要螺栓，而直接从电路板取下的电池夹不需要接线。 本发明还具有两种校准模式。 “段添加”模式允许将电压/浓度曲线分离成单独绘制的区域，其数量取决于在校准过程中使用的参考溶液的数量。 使用与样品溶液的测量电位最接近的部分来计算浓度。 在替代的校准模式中，使用一个或多个参考溶液来建立与预期的已知值进行比较的计量电压/浓度组合。 它们之间的任何差异提供与可用于更准确地限定电压/浓度曲线的取向的装置相关联的“噪声水平”值。

The segment corresponding most closely to the measured potential of a sample solution is used to calculate concentration. In an alternative calibration mode, one or more reference solutions are used to establish meterd voltage/concentraiton combinations that are compared with expected, known values. Any discrepancies therebetween furnish a "noise level" value associated with the apparatus that can be used to move precisely define the orientation of the voltage/concentration curve.
