| Abstract: | A new instrument for testing trace bacteria in bottled drinking water online by fluorimetry was introduced,and the autonomatic control system was designed. Through using operational amplifier ICL7650, second-order reverse-phase low pass filter, embedded MCU with high performance and testing programm in the instrument, the real-time testing could be ensured and the immediate sampling inspection could be possible. |
