The ONETEST-501S-II air negative (oxygen) ion sensor is an economical negative ion sensor developed by Wanyi Technology for measuring the concentration of negative ions in indoor and outdoor ambient air. It is particularly suitable for measuring negative ions in materials in the home decoration market, indoor air negative ion measurement, IoT integration, and other fields, such as indoor air, negative ion coatings, boards, fabrics, and other materials that release negative ion concentrations.
The ONETEST-501S-II air negative (oxygen) ion sensor adopts the universal flat plate capacitive electrode measurement principle, which has good oxidation resistance and fast response characteristics. Simultaneously sampling standard components imported from Germany and intelligent sampling fans, controlled by a microcontroller system, enables the instrument to achieve good stability and consistency! Suitable for measuring negative ions in the environment and evaluating environmental air quality! It is a good measurement tool for intelligent IoT monitoring, device integration, home decoration, green building materials, negative ion products, and other related fields!
