Design of axial cylindrical electrode for onetest-502xp-a multi parameter negative oxygen ion detector

Overview of Multiparameter Negative Oxygen Ion Detector
The ONETEST-502XP-A multi-parameter negative oxygen ion detector adopts a coaxial cylindrical electrode design, which has advantages such as stable sampling airflow, uniform ion distribution measurement, and strong anti-interference ability; Accurately measure small particle size positive and negative ions from nature, as well as high concentration negative ions generated by negative ion generators and their products, and display the level of air quality; At the same time, an external multi-parameter module can be selecte to measure air quality parameters such as PM2.5, PM10, temperature, humidity, etc. It is an indispensable monitoring hardware component for building an indoor air quality monitoring system.
