Air negative oxygen ion formaldehyde PM2.5 detectorProduct Introduction:
The portable negative ion detector is a high-precision, professional air negative ion, formaldehyde, PM2.5, and PM10 detection and analysis instrument. Adopting an advanced cylindrical capacitor structure negative (oxygen) ion capture mechanism, the negative (oxygen) ions contained in the atmosphere are captured, and then precise statistical calculations are performed through a unique algorithm. It has the advantages of stable measurement process, rapid response, and accurate measurement results. At the same time, it has strong resistance to electromagnetic, electrostatic, and electromagnetic wave interference, and has extreme sensitivity and capture ability for small particle size negative ions, with excellent overall performance.
The portable negative ion formaldehyde detector is easy to operate, with a 5.0-inch full-color large screen displaying real-time measurement data, instrument working status, and automatic calculation of average values. Operators with zero foundation can quickly measure without professional training.

Air negative oxygen ion formaldehyde PM2.5 detectorProduct Application:
Real time measurement of atmospheric negative oxygen ion concentration, formaldehyde concentration pm2.5、pm10， It is the preferred tool for measuring and demonstrating the concentration of negative ions in environmental monitoring, nano coatings, negative ion health products, negative ion home decoration and building materials, indoor testing, air treatment, air purifiers and their products.

Working Principle:
Using the principle of "capacitive inhalation method" for negative ion detection, measure the concentration of negative ions in the air. Load a quantitative polarization voltage onto the polarizing plate (or bias plate) of the ion sensor (or collection barrel), and then allow the measured air to pass through the sensor at a constant speed according to the set speed. Specific small particle size negative ions in the air are deflected under the action of an electric field and captured by the collection plate. The collected negative ion negative charge can be processed by the collector to calculate the negative ion charge concentration value.
