Abstract
A dish-electrode concentration transducer unit of the type into whose dish one or a few drops of blood, on the order of 20-50 microliters, is dropped. The dish-defining structure of the transducer unit is thermally conductive, and both it and the transducer of the unit are thermostatically temperature-controlled, in order that the transducer and the blood being investigated be maintained at requisite temperature. The transducer is, in assembled condition of the transducer unit, held in place pressed against the thermally conductive dish-defining structure so as to be in thermally conductive engagement therewith. Accordingly, the transducer of the unit can be replaced with involvement of the heating element or temperature sensor of the thermostatic system of the transducer unit, and certainly without accompanying replacement of the temperature sensor.
