| Abstract: | An intelligent meter that measures pH,conductivity and turbidity has been designed for earthquake prediction research.Gave the design mechanism of the pH,conductivity and turbidity meter, focuses on the data acquisition circuit,pre-amplifying circuit,turbidity sensor,features of long-term stability and maintenance-free.The design of turbidity sensor is based on the theory of surface scattering and uses laser as light source.The meter has functions of man-machine conversation,data storage,serial communication,the design of parameter calibration and on-line measurement.The main rating and specifications were achieved.The instrument has run stably at an earthquake station for 3 months. |
