Disinfection Product

Winsen Technology has been focusing on gas sensor research for many years, and has a variety of ozone detection solutions, which can meet the application needs of different products in different environments.


Other Detector

Formaldehyde detector is an instrument for detecting formaldehyde. Generally, semiconductor sensors and electrochemical sensors are used to realize the rapid semi-quantification of formaldehyde in indoor air on the spot, which is characterized by simple structure, small size, intuitive,easy to carry and use.


Indoor Air Quality Monitoring

The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.
