Precalibrated, disposable electrochemical sensing devices can be constructed so as to utilize a housing shaped so as to internally include at least two separate half cells, one of which is capable of serving as a reference half cell and the other of which is capable of serving as a sensing half cell. The housing is shaped so as to include a top depression capable of being used as a container which is in communi-cation with the interiors of the half cells. The depression is capable of holding for a sample to be analyzed using the device. The housing is preferably mounted on a board which is capable of being plugged into a female socket. This board carries electrodes which are connected to electrodes in the half cells.
