Negative oxygen ion monitoring systemIt is a professional equipment that collects the concentration of negative oxygen ions in the air in real time through high-precision sensors, and can also expand the monitoring of temperature, humidity PM2.5、PM10、 Meteorological and environmental parameters such as wind speed and direction are commonly used in environmental monitoring, tourist attractions, ecological parks, indoor air quality management, and other scenarios.Negative oxygen ion monitoring systemThe core functions include:

Air quality assessment: Negative oxygen ions are known as the "air vitamin", and their concentration directly reflects the freshness of the air, providing health references for tourists and residents.

Ecological protection support: Through long-term data monitoring, analyze the impact of climate change and vegetation cover on negative oxygen ion concentration, and provide scientific basis for ecological restoration.

Disaster warning assistance: Combining meteorological data (such as rainfall and wind speed) to predict geological disaster risk areas and evacuate people in advance.

Intelligent management: supports remote monitoring, data storage, curve analysis, and threshold alarm, reducing manual intervention and improving management efficiency.

Technical principle:

The system achieves high-precision measurement based on ionization principle and capacitive inhalation method:

Ionization principle:

High voltage electric fields ionize air molecules, producing positive and negative ions.

By using ionization disappearance method or ionization current method, the number of negative ions per unit volume can be detected (such as negative oxygen ions adsorbed by the collection electrode to form a weak current, and the system calculates the current size to obtain the concentration value).

Capacitive suction method:

After the air sample is sucked into the detection chamber, ions are adsorbed onto the capacitor plates under the action of an electric field, forming an electric current.

Accurately calculate the concentration of negative oxygen ions based on air flow parameters.

The negative oxygen ion monitoring system has become an important tool in fields such as environmental protection, ecological construction, and tourism development. Its high precision, real-time performance, and multi parameter fusion provide strong support for scientific decision-making.
