The concentration of negative ions in the air is one of the signs that reflect the quality of air. my country has also incorporated negative ion indicators into the meteorological monitoring system. Therefore,
portable negative oxygen ion testers are often used in daily life such as; nano coatings, air purifiers , Negative ion generators, home decoration materials, etc., have a wide range of applications in the field of air environmental protection, but there are many types of negative oxygen ion testers on the market, the data is completely rewritten by the built-in program, and the data is completely unreliable!
What brand of portable negative oxygen ion tester? How to choose a model? What is the specific measurement principle?
Brand introduction: ONETEST/ Wanyi Technology is located in Guangming District, Shenzhen, a high-tech capital with convenient transportation and beautiful scenery. Guangmingcheng High-speed Railway Station is close at hand. Wanyi Technology was established in 2011, based on the first domestic "Indoor Air Quality Law" Established after promulgation. Shenzhen Wanyi Technology Co., Ltd. integrates research and development, sales, after-sales, and technical consultation, and drafted the corporate standard of "Negative Ion Detector".
Main product model: KEC-900+II series air negative ion detector is a multifunctional measuring instrument independently developed by Wanyi Technology. It is divided into three ranges: 2 million units/cm³, 20 million units/cm³, 200 million units/ cm³ is optional, ion mobility: 0.15cm²/V.sec, large, medium and small particle size ions can be detected, with maximum retention, average calculation and other functions, mainly used for: green negative ion building materials measurement and demonstration (negative ion plates, Measurement of coatings, etc.) Efficiency evaluation and testing of products such as universities, gardening departments, air purifiers, negative ion generators, atomizers, etc., and the measurement of other new negative ion materials can contact our company to send samples for measurement.

working principle:
Parallel plate type negative oxygen ion tester is a commonly used method that can meet the market's measurement needs.
A and B are a set of parallel and mutually insulated electrodes. There is a ring-shaped bipolar electrode at the top of the B pole. The air is sucked in by the built-in fan, and the negative ions in the air strike the electrodes at both ends of the A/B to discharge; the charge is transferred to the E ring electrode Self-discharge is formed, and the discharge signal is recorded, so that the number of positive and negative ions in the air can be measured.
