Abstract
PURPOSE: To measure electric conductivity and achieve the simplification and miniaturization of construction by discharging the charge having been stored in a capacitor through a measuring cell.
CONSTITUTION: The other ends of lead wires 4a, 4b whose one ends are connected to a pair of electrodes 3a, 3b constituting a measuring cell 1 are connected to both ends of a capacitor 7 through the normally open terminal 6a of a relay 5. After sample liquid is contained in a vessel 2, a switch 14 is turned ON to charge the capacitor 7. When the charging voltage reaches a specified value, a recorder 8 is operated and at the same time a switch 11 is turned on to changeover the traveling contact of the relay 5 to the normally open terminal 6a side thereby discharging the charge of the capacitor 7. The capacitor terminal voltage of this time is recorded. Thereby, the electric conductivity of the sample liquid is calculated by using the record values having been recorded in the recorder 8.
