1.What is Negative Oxygen Ion?

The abbreviation for negative oxygen ion is NAI, because the main component of NAI is negative oxygen ion, so NAI is often called negative air oxygen ion. Negative oxygen ions are a general term for individual negatively charged gas molecules and clusters of light ions.

2.Role of negative oxygen ion

NAI can destroy the barrier of bacterial viral charge and the activity of bacterial cell active enzyme.NAI, as one of the important members of active oxygen, has a strong redox effect due to its negative charge similar to superoxide radicals in structure; in addition, NAI can settle the suspended particles in the air. However, the concentration of negative ions is not the higher the better, when the concentration exceeds 106/cm3, negative ions will have certain toxic side effects on the body.

Negative air ions have a regulatory role in air purification and urban microclimate, and their concentration level is one of the indicators for urban air quality evaluation. Oxygen released by photosynthesis of plants is prone to photoelectric effect under short-wave ultraviolet radiation, forming oxygen negative ions.

Stay in a long time are closed room, people will feel dizzy, when we come to the forest beach, waterfalls and other places, we will feel refreshed, this is the role of negative air ions. Negative air ions, also known as negative oxygen ions, are negatively charged negative oxygen ions that gain excess paired electrons. It is formed when oxygen molecules in the air combine free electrons.

The discharge (lightning) phenomenon, photoelectric effect, fountains, waterfalls, etc. in nature can ionise the surrounding air and form negative oxygen ions. Negative oxygen ions in the medical profession enjoy "Vitamin", "air vitamins", "longevity factor",  and so on. Simply put, negative oxygen ions are a kind of natural tonic that cannot be seen or touched.

3.How to monitor negative oxygen ions?

So there will be people ask, said negative oxygen ions so good for human health, how do we know how much its concentration? This is to use the negative oxygen ion detector. Negative ion sensor is a set of high-precision collection of negative oxygen ions in the air and calculate the concentration value of the monitoring sensor, can be long-term, automatic, continuous, all-weather monitoring of negative ion concentration changes in the atmosphere, to adapt to the business needs of environmental meteorological observation, to meet the high precision and high stability of the observation data requirements.
