空气离子浓度仪是吸引空气(或者带有离子存在的气体)通过带电的平行极化电极板进行计数空气中的离子(气体)浓度的。外侧二板保持极化(正、负)电势。中间是线性检测器板。空气的孔隙是4MM，极化区的电势是1000V/M。即可测定正离子，又可测定负离子。也可以测定有关机体的负离子浓度，如布匹、纤维等。

The air ion concentration meter is to attract air (or gas with ions), and to count the concentration of ions (gases) in the air through the charged parallel polarized electrode plates. The lateral two plates maintain the polarization (positive and negative) potential. In the middle is a linear detector plate. The pore of the air is 4MM, and the potential of the polarization zone is 1000V/M. The positive ions can be determined and the negative ions can be determined. It can also be used to determine the negative ion concentration of the body, such as cloth, fiber and so on.
