negative ion detector of a small, high performance anion counter, has the characteristics of high sensitivity, high precision, high stability, big air volume using electrostatic shield and suction fan, even in an adverse environment ( Such as dust in the wind and the strong static electric field) Still can provide accurate readings. Can be used to detect natural or synthetic ion. Apply school unit, environmental protection system, negative ion research institutes and relevant units.
