Integrated screen-printed electrode detection handle with stirring function

The invention discloses an integrated screen-printed electrode detection handle with a stirring function. The detection handle integrates a screen-printed electrode, an external platinum-pair electrode, an external Ag/AgCl reference electrode, a stirring part and a testing cavity, wherein the stirring part is arranged among the screen-printed electrode, the external platinum-pair electrode and the external Ag/AgCl reference electrode; the stirring part comprises a miniature direct-current motor, a fixed bearing, a stirring rod and a connecting silicone tube; and the testing cavity is in threaded connection with a bottom cover of the handle. The integrated screen-printed electrode detection handle is connected with a portable heavy-metal detector or an electrochemical working station and the like to form a detection system, can be used for fast detection of heavy metals in water environment, has the characteristics that the structure is compact, the layout is reasonable, the installation is convenient, the replacement of the screen-printed electrode is convenient, the liquid addition is convenient and the detection sensitivity is effectively improved and the like, meets the portable need for detection of the heavy metal in the water environment, and has large application prospect.
