The proposed device for measuring concentration of light and heavy ions in air contains a measuring capacitor, a unit for feeding air, a voltage source, a resistance box, a measuring resistor, and a grid. The measuring capacitor contains an external electrode, which is designed as a brass tube, and an internal electrode, which is installed in the tube. The internal electrode is designed for measuring the concentration of negative light ions. The measuring resistor is designed for measuring the concentration of positive light ions. The resistor is inserted between the voltage source and the external electrode of the measuring capacitor. The grid is designed for measuring the concentration of heavy ions. The grid is arranged between the external electrode and the external electrode of the measuring capacitor.
