Abstract :
A method is presented for the development of the PC-based multi-biosensor system for detecting various components of the aqueous solution by measuring the DO (dissolved oxygen) concentration. The system consists of 6-channel signal conditioning circuits for the multi-cathode type DO sensor probe and PC interface circuits using the single chip microcontroller 80c196kc. Typical polarograms for the DO probes under test using this system are presented. This system covers a wide range of measuring time from 300 seconds to over 16 hours in one measurement step by programming the 9 monitor display modes
