Nederlands Air quality isn’t something we can see, but it’s something we breathe in every moment of every day. Whether you’re at home, in a workspace, or outdoors, the air around you can carry dust, chemicals, and gases that affect your health — sometimes in ways you don’t notice right away.
That’s where air quality monitors come in. These devices help us understand what’s in the air, so we can take action when needed. But with so many different types on the market, how do you pick the right one? This guide breaks down the basics — what air quality monitors are, why they matter, and how to choose one based on where and how you plan to use it.
What Is an Air Quality Monitor?
In simple terms, an air quality monitor is a device that detects pollution and other gases in the air. The catch? “Air quality” is a broad term. Depending on the model, a monitor might track particles like PM2.5 and PM10, gases like CO₂, carbon monoxide, formaldehyde, or even volatile organic compounds (TVOCs).
A good air quality monitor typically includes a combination of sensors that give you a snapshot of indoor or outdoor air conditions. Some are compact and portable, while others are meant for fixed, long-term use.
Why Test the Air?
We tend to think of air as clean unless there’s visible smoke or a strong odor. But air can carry harmful substances even when it looks fine. A typical clean atmosphere is made up of about 78% nitrogen, 21% oxygen, and less than 1% of other gases — including pollutants. That tiny percentage can make a big difference.
Each day, we breathe in around 10–12 cubic meters of air. Unlike food or water, we can’t survive without air for more than a few minutes. So knowing what’s in the air isn’t just a curiosity — it’s about protecting your health and improving your environment.
Choosing the Right Air Quality Monitor for Your Environment
Different situations call for different tools. Here’s a breakdown of the most common types of air quality monitors and where they shine.
🏡 Wall-Mounted Indoor Air Monitor
- Ideal for: Warehouses, factories, archives, and cleanrooms
- What it tracks: PM2.5 and PM10
- How it works: Uses light scattering to detect particulate concentration — the more particles in the air, the more light is scattered.
Built for tougher environments, this model often features a sealed, dust-resistant casing for protection and longer lifespan
🌀 Multifunction Indoor Air Quality Monitors
- Ideal for: Hospitals, schools, airports, smart buildings
- What it tracks: PM2.5, PM10, CO₂, CO, O₂, CH₂O, TVOC, temperature, humidity, barometric pressure, and more
- Design: Sleek, disc-shaped housing with multiple air vents for accurate readings
- Benefits: Combines multiple measurements into one device, saving on installation and maintenance
If you’re managing air quality for a larger space or building system, this type is your all-in-one solution.
🚶♂️ Portable Air Quality Monitors
- Ideal for: Field inspections, confined spaces, emergency response
- What it tracks: Customizable — can include PM2.5, PM10, CO, CO₂, O₃, NH₃, SO₂, etc.
- Types:
- Diffusion type — passive sensing, affected by airflow
- Pumping type — active air intake, more accurate and responsive
- Extras: Comes in a hard case, supports external air pumps for special applications
These are designed for people on the move — whether you’re testing in different rooms, out in the field, or inside hard-to-reach ducts and enclosures.
🌤️ Outdoor Air Quality Monitors
Solar Radiation Shield Air Quality Monitor
- Ideal for: Weather stations, outdoor environmental monitoring
- Design: Louvered, white ABS shell that protects sensors from rain, sun, dust, and UV
- Features: Works with weather stations, low maintenance, built to last outdoors
If you’re setting up long-term air monitoring outside, this is your go-to. It’s weather-resistant and allows for free air circulation to ensure accurate measurements.
🛠️Pipe mounted
The ES-GXXXP series includes transmitters for CO, CO₂ (including wireless and industrial wall-mounted types), O₂, O₃, SF₆, H₂S, NH₃, SO₂, NO₂, TVOC, PH₃, H₂, CH₄, CH₂O, and more.
They feature imported sensors with fast response, high accuracy, and strong anti-interference. The waterproof, pipe-mounted design supports optional OLED display and resists electromagnetic interference. Multiple output options are available, including RS485 and analog (4–20 mA / 0–10 V / 0–5 V).
