計。1. An electrolyte solution densitometer utilizing an ionizing action, comprising a cup-shaped liquid reservoir for containing a liquid to be measured,
The side wall of the liquid pool has an electrode of either one of the anode or the cathode, and the bottom surface of the liquid pool has an electrode other than the electrode provided on the side wall, Furthermore,
A measuring unit that has a sensor unit formed by both of these electrodes, measures the data (signal) related to the voltage detected by the sensor unit, and the data (signal) measured by the measuring unit is used to measure the solution concentration. Calculation means for converting to data (M
PU) and the like, and a display means for displaying the measurement result of the liquid to be measured based on the signal from the control means.
