Negative oxygen ion detector

HM-FY2 negative oxygen ion detector

Features: mobile measurement | instant on/off measurement | intuitive reading | simple operation | ultra long standby time

Product Introduction:

HM-FY2 negative oxygen ion detector is a high-precision and professional air negative ion and formaldehyde detection and analysis instrument. Adopting an advanced cylindrical capacitor structure with a negative (oxygen) ion capture mechanism, the negative (oxygen) ions contained in the atmosphere are captured and then statistically calculated using 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, excellent sensitivity and capture ability to small particle size negative ions, and overall superior performance.

The HM-FY2 negative oxygen ion 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.

Product application:

Real time measurement of atmospheric negative oxygen ion concentration and formaldehyde concentration in the air is a preferred tool for environmental monitoring, nano coatings, negative ion health products, negative ion home decoration materials, indoor testing, air governance, air purifiers and their products to measure and demonstrate negative ion concentration.

Working principle:

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