AQ Guard system: the air we breathe 

Everyone breathes 12 m³ of air daily, including all the pollutants in it. This alone should draw our attention to the quality of the air we breathe. 

Why air pollution must be measured 

Contamination of the air with fine and ultrafine particles has become one of the greatest health risks worldwide. According to the World Health Organization (WHO), particulate pollution increases the risk of heart attacks, strokes and lung cancer, as well as many other diseases. On average, each person worldwide loses three life years due to polluted air. 

Our solution to the challenge: AQ Guard 

Increasing the geographic coverage and density of an existing air quality monitoring network should not reduce data quality. Using low-cost sensors can raise serious doubts about overall data validity and integrity. The solution: compact, advanced particulate measuring devices equipped with the same technology as type-approved analyzers for monitoring indoor and outdoor air pollution. 

Small device. Big power. 

Knowledge is power. Know what air you breathe. 

Palas® AQ Guard and AQ Guard Ambient provide accurate, reliable indoor and outdoor air quality data. Make decisions based on accurate information. 

The new standard for compact particulate monitors 

AQ Guard is a compact, stationary fine dust monitor equipped with the unique Fidas® 200 optical particle sensor. The principle of counting and measuring individual particles, and the highly effective aerosol drying technology of Palas® ensure precise measurements under all conditions, even at 100% relative humidity (rH). AQ Guard sets the standard in its class. 

Versatile, reliable and stable 

AQ Guard is not only the most advanced compact particulate monitor, it also allows you to manage application-specific requirements based on your choice of function. Thanks to advanced self-diagnostics, AQ Guard provides up to two years of reliable data without calibration. This not only means you can trust the data, but it also helps reduce operating costs. 

AQ Guard 

AQ Guard combines advanced technology and an attractive design that integrates elegantly into offices, public spaces or vehicles. 

An integrated display and various interfaces provide access to PM2.5 and PM10 data, with optional high-resolution particle size distribution. 

Healthy Rooms package 

Through the Healthy Rooms package, you can expand the AQ Guard with sensors for carbon dioxide and volatile organic compounds. Healthy Rooms includes a unique feature for indoor air monitoring: the germ indicator (patent application pending), an innovative combination of sensor technology and software, which visualizes the likelihood of air pollution with potentially infectious exhaled particles.
