Abstract (in english)
   A new procedure has been tested for the treatment of the alternating signal coming from a contactless conductivity detection cell. An unmodulated or an amplitude-modulated a.c. voltage is applied to the cell and the a.c. current passing through the cell is treated by a TDA 1072A integrated circuit, obtaining a signal depending on the conductivity of the quiescent or flowing solution inside the cell. The detector was used to measure the conductivities of various drinking waters and the values obtained were in a good agreement with those provided by a commercial contact conductometer.
