FIELD: physics, instrumentation technology.
SUBSTANCE: invention relates to measurement technology and can be used to measure ion concentration of atmospheric air. In the device for counting ions, comprising an aspiration chamber, the high-voltage electrode of which is connected to a high-voltage power source, and the collecting electrode, through a switch controlled by the signal of a control device, is connected to the input of the output device, and a display device, the novelty lies in that it further includes series-connected band-pass filter, analogue signal rectifier and low-pass filter, the output of which is connected to the input of the display device, and the input of the band-pass filter is connected to the output of the input device.
EFFECT: invention provides high accuracy of measuring ion concentration by reducing the impact of interference.
