Monitoring Indoor Air Quality

Breathe Easy Knowing What Is In Your Space

Monitoring indoor air quality is essential for the health, safety, and comfort of people in a space. Met One Instruments offers several portable and bench-top particle counters and indoor air quality monitoring solutions that provide a convenient and portable way to test indoor air quality, spot check or verify cleanrooms, and test HVAC air filter efficiency. Our air quality monitoring instruments such as our handheld or benchtop particle counters and mass monitors are cost-effective, accurate and reliable. One-touch monitoring makes these devices fast and simple to use. Met One also offers a portable dust monitor designed to measure and record information in a space continuously. Our instruments are well-suited for corporate offices and manufacturing spaces, as well as residential, school and public areas.

We Spend on Average Approximately 90% of our Time Indoors…

The demand for accurate and reliable indoor air quality monitoring instrumentation continues to grow as we spend more time indoors than ever before. However, indoor air quality issues can be complex due to the diversity of indoor environments and outdoor pollution infiltration. Particle counts and mass concentration readings are critical to determining the overall air quality in indoor settings. Assessment of the air quality in your indoor environment should begin with dependable, professional-grade air quality monitors, like the equipment manufactured by Met One Instruments Powered by Acoem.

Protect Health and Safety Through Emissions Sourcing

Obviously, air quality and having clean healthy air to breathe is a significant concern to everyone. Air quality impacts the health, comfort, wellbeing, and productivity of occupants in any space. Even outside. Industrial hygienists, toxicologists, chemists, engineers, physicians, and other Environmental Health & Safety professionals dedicate their careers to ensuring people are kept safe and healthy in their workspace or public venue. Providing a safe air space for people to breathe healthy air is a significant component of the bigger sustainable picture in any setting.
