Multi-channel recorder for I-V curves

The operation of nine – channel microprocessor controlled recorder to be used for concurrent recording of current – voltage characteristics in two or three electrode configurations has been described in the present study. The prototype version of the recorder as been designed for measurements associated with determination of oxygen stream density in the course of soil oxygen micro-diffusion. The common setting of measurement parameters in the scope of three measuring channels is possible by means of recorder operation program enabling the execution of the measurement in three measuring groups which are independent of each other. The measurements in cycles lasting several days with automatic measurement results recording are possible by means of the recorder.
