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.

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.
