摘要： An electrochemical cell is formed by immersing an electrochemical ion sensor and a reference electrode into a solution of interest, the electrochemical ion sensor exhibiting ion selectivity with respect to an ion of interest and having a high electrode resistance. A current which flows through the electrochemical cell is measured while the potential of the electrochemical ion sensor is held to a constant potential with respect to the reference electrode. The current so obtained are proportional to the logarithm value of the concentration of the ion.

摘要： A biological information measurement apparatus is adapted to measure biological information in an extracorporeal circuration or in a living body by various measurement circuits comprising circuit elements which are not affected by electrical disturbances, and to transmit the results of measurement in the form of a non-electrical signal which is not affected by electrical disturbances. Measured values from measurement sections are gathered at a central processing section separated from the measurement sections. The processing section converts the measured values into output values, compensates the values for temperature and outputs the values to a display unit and recorder.
