<p>Precalibrated, disposable electrochemical sensing devices (20) can be constructed so as to utilize a housing (26) shaped so as to internally include at least two separate half cells (80,82), one of which is capable of serving as a reference half cell (82) and the other of which is capable of serving as a sensing half cell (80). The housing is shaped so as to include a top depression (60) capable of being used as a container which is in communication with the interiors of the half cells. The depression is capable of holding a sample to be analyzed using the device. The housing is preferably mounted on a board (22) which is capable of being plugged into a female socket. This board carries electrodes (28,30,32) which are connected to electrodes in the half cells.. <IMAGE></p> |
