Abstract: In order to improve the precision, stability and reliability of on-line dissolved oxygen(DO) survey meter, the hardware and software system for a new optic fiber DO on-line measuring instrument were developed based on fluorescence method. ARM7 was used as the main control unit to improve its precision, stability and reliability. Precise data of DO could be accurately and continuously detected and the measured values could be shown on LCD display. The test results indicate that the measurement system has good stability, anti-interference ability and high practical application value.
