Portable negative (oxygen) ion detector

Before using an instrument, it is necessary to have a complete understanding of it, so that accurate monitoring data can be obtained by appropriate methods when using the instrument. Different kinds of instruments have different functions, and the working principle used is also different. This paper introduces a portable negative oxygen ion detector.

Introduction to portable negative oxygen ion detector

Portable negative (oxygen) ion detector is a kind of air negative ion detection and analysis instrument with high precision and good professional degree. It is made of the negative (oxygen) ion capture mechanism of the cylinder capacitor structure, and can capture the negative (oxygen) contained in the atmosphere after starting, when the air flows into the instrument, through special algorithms, statistics and calculations, accurate results can be obtained. The portable negative oxygen ion detector has the characteristics of stable measurement process, fast reaction and accurate measurement results. At the same time, it also has strong ability to resist electromagnetic, static and electromagnetic interference in practice. For small particle size negative ion sensitive and capture ability is also very strong, the overall performance of the instrument is higher.

The portable negative oxygen ion detector uses the principle of "capacitive suction method" to detect the negative ion content, and can accurately measure the negative ion concentration value in the air. The polarization of the ion sensor (or acquisition bucket, acquisition barrel) can increase the quantitative polarization voltage, so that the measured air can pass uniformly through the sensor at a set speed. At this time, the specific small particle size negative ions in the air can be deflected under the action of an electric field, and the acquisition board will capture these small particle size negative ions. The negative ion charge concentration value can be obtained after being treated by the collector.
