On-line monitoring system of negative oxygen ion concentration

Negative ions are colorless, odorless, negatively charged, highly adsorbent and propagate in the air. Every day of human life can not be without the existence of negative ions, she and we have gone through tens of thousands of years of life mileage, to become a partner in human life.

Negative ions are also known as "air vitamins", like vitamins in food, play a very important role in human and other biological life activities, and even some people associate air negative ions with longevity, called "longevity hormone".

Forests, wetlands and other natural environment formed by high oxygen rich areas, with water molecular impact areas formed by water fall, fountains, waterfalls and other surrounding environment formed by high negative oxygen ion concentration, are very conducive to people's health.

An environment with a high concentration of negative oxygen ions may not be conducive to human health. The concentration of negative oxygen ions is affected by many factors such as geographical environment and the change of meteorological elements.

The basic principle of air negative ion concentration test is: Under the action of the getter, the air flows evenly through the ion collector and at the same time, a certain voltage is applied to the polarization plate of the ion collector to form a potential difference inside the collector and an electric field is formed, so that the air negative ions are offset in the direction of the collector plate by the electric field force. When ions hit the collector plate, a discharge will occur and a current will be formed. Then the current is measured by the current testing circuit and the corresponding air negative ion concentration is obtained through the calculation of the relevant formula.

The online monitoring system of negative oxygen ion concentration mainly includes hardware and software. The hardware has monitoring module, data acquisition transmitter and peripheral equipment, and the software has instrument background communication software and ion data analysis software.
