Portable negative oxygen ion detector

YT-FY02 portable negative (oxygen) ion detector：

Features: | Mobile measurement | Instant measurement | Intuitive reading | Easy operation | Long standby time|

The YT-FY02 portable negative (oxygen) ion detector is a high-precision and professional air negative ion detection and analysis instrument. Adopting internationally leading coaxial double cylinder technology, 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 YT-FY02 portable negative (oxygen) ion detector is easy to operate, with a full-color large screen displaying real-time measurement data, instrument working status, historical data curves, and automatic calculation of maximum, minimum, and average values. Operators with zero foundation can quickly measure without professional training.

operational 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.
