AN-500 portable negative (oxygen) ion detector

Using the principle of "capacitive inhalation method" for negative ion detection, measure the concentration of negative ions in the air. Load a quantitative polarization voltage onto the polarizing plate (or bias plate) of the ion sensor (or collection barrel), and then allow the measured air to pass through the sensor at a constant speed according to the set speed. Specific small particle size negative ions in the air are deflected under the action of an electric field and captured by the collection plate. The collected negative ion negative charge can be processed by the collector to calculate the negative ion charge concentration value.
