Air negative oxygen ion formaldehyde pm2.5 detector product introduction:

Air negative oxygen ion formaldehyde pm2.5 detector is a high-precision, professional air negative ion, formaldehyde, pm2.5, pm10 detection and analysis instrument. It uses an advanced cylindrical capacitor structure negative (oxygen) ion capture mechanism to capture negative (oxygen) ions contained in the atmosphere, and then performs precise statistical calculations 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, static electricity and electromagnetic wave interference, has excellent sensitivity and capture ability to small particle size negative ions, and has superior overall performance.

The Air negative oxygen ion formaldehyde pm2.5 detector is easy to operate. The 5.0-inch full-color large screen displays real-time measurement data, instrument working status, and automatically calculates average values. Operators with zero knowledge can quickly measure without professional training.

Air negative oxygen ion formaldehyde pm2.5 detector product application:

Real-time measurement of atmospheric negative oxygen ion concentration, formaldehyde concentration, pm2.5, pm10 in the air is ideal for environmental monitoring, nano-coatings, negative ion health care products, negative ion home decoration and building materials, indoor testing, air management, air purifiers and their products negative ion concentration The ultimate tool for measurement and presentation.

Air negative oxygen ion formaldehyde pm2.5 detector working principle:

The principle of "capacitive inhalation method" is used to detect negative ions and measure the concentration of negative ions in the air. A quantitative polarization voltage is loaded on the polarization plate (or bias plate) of the ion sensor (or collection barrel, collection tube), and then the measured air passes through the sensor at a constant speed at a set speed. Specific small-sized negative ions in the air are deflected under the action of the electric field and captured by the collection plate. The collected negative ions and negative charges are processed by the collector, and the charge concentration value of the negative ions can be calculated.
