Description

technical field

[0001] The invention relates to an air ion measuring method and an air ion measuring instrument, in particular to an air ion static measuring method and an air ion static measuring instrument. Background technique

[0002] In 1889, German scientists Elster and Gertel discovered the existence of negative air ions, and in 1902, Ashamas and others affirmed the biological significance of the existence of air ions. The role of air negative ions has been recognized by the medical community. In addition to being beneficial to human health, it also has the functions of sterilization, dust removal and deodorization. The monitoring of air ions in the world usually uses a fan to make air pass through a parallel plate capacitor (i.e. air ion collector) at a certain flow rate, and a certain voltage is applied to the capacitor to allow the capacitor to capture air ions, and then detect the discharge current of the capacitor (or voltage) method to measure, as in the utilit...
