Introduction to handheld negative oxygen ion detector

Introduction of handheld negative oxygen ion detector - In recent years, with the deepening of research on air negative ion concentration monitoring system in meteorological, environmental protection, forestry and other departments, handheld negative oxygen ion detector has become a popular equipment, which is mainly used in the determination of specific negative ion concentration value in the air, especially suitable for the determination of small particle size negative ion concentration value. At the same time, it can also be used to determine the concentration of small and medium particle size positive ions in air.

The handheld negative oxygen ion detector is an instrument designed for detecting the concentration of negative oxygen ions and its lighter mass. It adopts the "capacitive suction method" and uses the capacitive air ion collector to collect the charge carried by the air ions, and measures the current generated by these charges and the flow in the sampling air, and finally converts the ion concentration into a measurable value.

Using the handheld negative oxygen ion detector, we can have a more comprehensive understanding of the quality and characteristics of the air, thereby improving the awareness of air quality. It is a portable instrument that can be used to detect whether the indoor air contains negative oxygen ions or oxygen content. In contemporary society, people are often in the indoor environment, and some indoor environments often have quite serious air pollution problems. In these environments, air is one of the most important components. In offices, classrooms, hospitals and other places, there are a large number of pollutants, including but not limited to formaldehyde, benzene and other harmful substances, which pose a great threat to the environment and human health. Therefore, the use of negative oxygen ion detectors in these occasions to improve air quality is very necessary. In addition, the negative oxygen ion detection instrument has high precision and real-time performance, which can detect the content of negative oxygen ions in the air in real time, so as to accurately determine the required air purification conditions and ways.

Using a 5-inch capacitive touch screen, the handheld negative oxygen ion detector can present measurement data in real time, and the operation is simple and intuitive, and the test results are intuitive and easy to understand, and the test can be quickly completed with simple training without professional skills. This paper introduces a portable air anion detector controlled by single chip computer. The instrument can detect the air negative ion concentration, formaldehyde concentration, temperature and humidity, and the content of pm2.5,pm10 in real time, which provides important support for air treatment and other negative oxygen ion measurement, and is also one of the commonly used tools in the measurement of negative ion concentration.
