Abstract
Abstract A miniature probe contains multifunctional electrochemical electrodes which measure both specific ion activities of samples and the carbon dioxide or oxygen activity of samples. The miniature probe includes a carbon dioxide sensor or an oxygen sensor. When the specific ion electrode of the probe is connected to an external reference electrode, a specific ion sensor is provided.
