APPLICATION
Winsen is a world-renowned gas sensor manufacturer and supplier. A variety of sensors are intelligently combined and developed to form the overall concept of the module. The extremely flexible assembly combination can meet the sensitivity, corresponding speed, stability, power consumption and size requirements of all air purifiers on the market.
Winsen Technology has provided accurate gas detection solutions for more than 1,000 fresh air enterprises, which has also established the influence of Winsen sensors in the air purification market. In the future, Winsen will launch more intelligent and miniaturized all-in-one integrated modules to meet the various needs of different customers in the ventilation system market.
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.
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.
