METHOD OF MEASURING THE CONCENTRATION OF IONS AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC H01J47/04 

FIELD: measuring equipment.

SUBSTANCE: use: to measure the concentration of air ions. Essence of the invention lies in the fact that the method of measuring the concentration of ions lies in the periodic accumulation of charge on the capacity of the aspiration chamber during the deposition of ions of the test air on its collecting electrode for equal periods of time and its subsequent measurement. Ion concentration is determined by the number of voltage pulses that occur when the capacity of the aspiration chamber is discharged to the inductance, the amplitude of which is greater than a certain specified value according to the specified expression.

EFFECT: providing opportunities to improve measurement accuracy and reduce hardware costs.
