Negative Ion Detection Module-ITS-01 Measure The Negative Ion Generator Air Purifier

1.Overview
    Negative ion detection module - ONETEST-ITS01 negative ion detection sensor module is designed to measure the concentration of negative ions in negative ion generators and air purifiers. It is designed with standard components with strong anti-interference and can measure the concentration of negative ions between 10,000 and 30 million. It is suitable for rapid inspection of negative ion generators, equipment integration of air purifier devices and high-concentration generators in fresh air systems.
