ABSTRACT:
In an electrochemical apparatus utilizing an electrochemical cell having a solid-electrolyte and at least one pair of porous electrodes arranged in contact with the solid-electrolyte, wherein one electrode of the pair of electrodes is exposed through a diffusion means having a diffusion resistance with respect to a gas to be measured in a space in which the gas to be measured is present, and an atmosphere near one of the electrodes is controlled by an electrode reaction due to a current flowing through the pair of electrodes, a first branch conductor and a second branch conductor are formed by dividing one of conductors respectively connected to the electrodes, and at least one adjustable first resistive means and at least one second resistive means are respectively formed in the first branch conductor and the second branch conductor. Therefore, a predetermined current flows through either the first or second resistive means, and thus it is possible to obtain the electrochemical apparatus which maintains a constant quality in large scale manufacturing.
