The Portable Multifunctional Environmental Negative Oxygen Ion Detector is a high-precision, professional-grade instrument for analyzing air negative ions, formaldehyde, PM2.5, PM10, temperature, and humidity. It employs an advanced cylindrical capacitive structure negative (oxygen) ion capture mechanism to trap negative (oxygen) ions from the atmosphere, then performs precise statistical calculations via proprietary algorithms. It offers advantages such as stable measurement processes, rapid response times, and accurate results. It also exhibits strong resistance to electromagnetic, electrostatic, and electromagnetic wave interference, with outstanding sensitivity and capture capability for small-particle-size negative ions, delivering superior overall performance.
The FY4 Portable Multi-Functional Environmental Negative Oxygen Ion Detector is simple to operate. Its 5.0-inch full-color display shows real-time measurement data, instrument status, and automatically calculates averages. Operators with no prior experience can perform measurements quickly without specialized training.
This multifunctional environmental negative oxygen ion detector provides real-time measurements of atmospheric negative oxygen ion concentration, formaldehyde concentration, PM2.5, PM10, temperature, and humidity. It serves as an optimal tool for environmental monitoring, nano-coatings, negative ion health products, negative ion home decoration materials, indoor testing, air treatment, air purifiers, and related products requiring negative ion concentration measurement and demonstration.
The Multi-Functional Environmental Negative Ion Detector employs the “capacitive inhalation method” principle to detect negative ions, measuring their concentration in the air. A specific polarization voltage is applied to the polarization plate (or bias plate) of the ion sensor (also known as the collection bucket or collection cylinder). The air sample is then passed uniformly through the sensor at a preset velocity. Under the influence of the electric field, specific small-particle-sized negative ions in the air deflect and are captured by the collection plate. The collected negative charge from the ions is processed by the collector, enabling the calculation of the negative ion charge concentration value.
