Air quality testing instruments, handheld environmental protection guards

Environmental challenges such as haze and dust storms are becoming more prevalent and affecting our daily lives. Masks have transformed from a temporary protective measure to a regular part of our daily lives. Public concern over air quality continues to rise. According to the World Health Organisation, indoor and outdoor air pollution is the biggest environmental health risk globally. According to its statistics, air pollution causes about 6.5 million deaths globally each year, with air pollution claiming about 600,000 lives annually in Europe.

Monitoring and improving air quality is crucial to improving people's health by reducing deaths caused by air pollution, as well as lowering the risk of major diseases such as heart disease, lung cancer, stroke and chronic respiratory diseases including asthma.

The invisible nature of air makes it difficult to visually recognise air quality, which increases the difficulty of managing it effectively. Prolonged exposure to polluted air, especially in indoor public places such as offices and classrooms, poses a particularly serious threat to human health. Therefore, the use of scientific and efficient air quality control methods is essential to protect people in these places.

The air quality testing instrument FT-FY4 is a portable device designed for quick air quality measurement. It is capable of detecting key indicators such as negative oxygen ions, formaldehyde, PM2.5, PM10 and temperature and humidity in the air.

This device has the following features:

1. Portability: handheld design, easy to carry and use on site.

2. Intuitive display: equipped with a 5-inch touch screen, real-time display of measurement results.

3. Long-lasting battery: Built-in lithium battery, support long time continuous work.

4. Anti-interference: with good anti-electromagnetic and electrostatic interference ability to ensure the accuracy of measurement data.

It is suitable for indoor and outdoor air quality monitoring, ideal for environmental testing, indoor air quality assessment and air purification product testing, helping users to understand and improve air quality in a timely manner to protect health.
