Electro-chemical device with ion-sensitive elements for measurement of parameters of solutions relates to measuring engineering and can be used at development of devices and systems for investigation or analysis of materials through determination of electro-chemical parameters of those. It includes indicator and support element first electrodes of which are connected to inputs of the first and the second transformer current-voltage, respectively. Second electrodes of indicator and support element are connected to the first contact of the first source of support voltage second contact of which and third electrodes of indicator and support element are connected to common bus. Information input of the device is information input of indicator. Outputs of the first and the second transformer current-voltage are connected to the first inputs of the first and the second adder, respectively, second inputs of those are connected to the first output of the second source of support voltage second output of which is connected to common bus. Outputs of the first and second adders are connected through the first and the second integrator to the first and second inputs of the subtraction block, respectively, output of which is connected to output of the device. Electrochemical device with ion-sensitive elements for measurement of parameters of solutions makes it possible to increase accuracy of measurement due to decrease of level of noise and errors at outlet of the device and more complete use of dynamical range of measuring section and to simplify adjustment through decrease of number of parameters that are controlled and adjusted. |
