A ‘low cost’ air quality monitor, the AQY gives you air quality information that’s scientifically credible, and relevant to where you live, work and play. Set up as a single device or deployed as a network of monitors, the AQY reports key urban pollutants in real-time. Use the AQY for:
- Smart city grid monitoring
- Mapping pollution sources
- Roadside monitoring networks
- Community exposure studies
- Protecting health and safety of students
- Validating air quality models
The 千部毛片免费观看_美女网站免费视频 AQY multi-sensor units performed very well compared to more expensive FEM/FRM instruments and overall showed excellent correlation for ozone, and very good correlation and high accuracy for NO2 and PM2.5.AQ-SPEC: Air Quality Sensor Performance Evaluation Center, South Coast AQMD
WHO IS IT FOR?
The AQY air quality monitor produces scientifically credible data, yet is simple to set up and use. Designed for:
Smart cities who want air quality and environmental data to show that their city is an attractive place to live, work and invest in.
Air quality professionals who need a real-time alternative to diffusion tubes and samplers, or a more affordable alternative to analyzers.
Community groups who need a cost-effective way to gather scientifically credible air quality data that will be treated with respect by their stakeholders.
Educators who want students to learn about air pollution in a way that supports STEM subjects and promotes environmental awareness.
Health and safety managers who need to demonstrate that they are providing a safe environment for the people in their care.
Researchers who want to collect as much scientifically robust air quality data as possible on a limited budget.
WHAT DOES IT MEASURE?
The AQY measures the main pollutants found in urban environments: particulate matter (PM2.5), ozone (O3) and nitrogen dioxide(NO2). These three pollutants are known to have the biggest impact on people who live in cities and the health effects have been well-documented.
- Particulate matter (PM2.5)
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Relative humidity
- Dew point
HOW DOES IT WORK?
Solar shield with high reflectivity, external vent and internal heat stabilization.
Humidity & temperature compensation
Improves measurement quality in humid conditions for PM and NO2 sensors.
Data is collected in real-time, allowing immediate identification of the operational status of sensors.
Correction on device
All measurement correction is done on the device, which increases confidence in the scientific validity of the data.
Ozone sensor rejects NO2, temperature and RH, which commonly trouble other ozone sensors; NO2 sensor rejects ozone, which commonly troubles electrochemical NO2 sensors.
Wirelessly sends data to you in real-time.
Long-life PM laser lowers cost of servicing; flow compensation maximizes useful life of sensor in high PM conditions.
Dual calibration of PM2.5 and to NIST traceable standard and true NO2 factory calibration provides scientifically valid measurement.
Ensures a more representative measurement of ambient air for ozone and PM.
Improves quality of signal especially at low ppb levels.
Built from stainless steel, PFA and PTFE materials that ensure no target analyte is lost.
GSS ozone technology
千部毛片免费观看_美女网站免费视频’s industry-leading tech that people rave about.
Minimizes particle matter loss in the sampling system.

Step 1 – Set up your AQY
The AQY can be mounted to a wall, pole or railing. Though intended to operate in a fixed location, the quick set up time means it can be easily relocated. Install somewhere with good airflow and away from emission sources e.g. vents.
Step 2 – Gather data
Particulate matter, gas and environmental parameters are recorded by the AQY air monitoring device simultaneously and in real time. The AQY reports data in 1-minute intervals and has on board storage for over 5 years of data.
Step 3 – Analyze data
Analyze your data to identify trends and map pollution sources. Users can view where your monitors are located on a map, average data and do deep analysis by plotting charts with data from multiple devices.
HOW DOES IT PERFORM?
千部毛片免费观看_美女网站免费视频 takes a measurement-first approach, offering an air quality monitoring device that produces scientifically-credible data. The AQY has been tested in a range of environments: New Zealand (very low pollutant levels), Beijing (very high pollution levels), Southern China (high humidity and temperature), as well as Los Angeles (a bit of everything).
Results from a field evaluation by AQ-SPEC (Air Quality Sensor Performance Evaluation Center) in L.A. compared data from the AQY (v0.5) to that of Federal Reference Methods (FRM) and Federal Equivalent Methods (FEM).
- Ozone (O3) sensors showed an excellent correlation with a more expensive instrument: R2 >0.95
- Nitrogen dioxide (NO2) sensors showed a very good correlation with a more expensive instrument: R2 >0.74 and high accuracy
- Particulate Matter (PM2.5) sensors showed a very good correlation with more expensive instruments: GRIMM R2 >0.84 and BAM R2 >0.83 and high accuracy
- Temperature and relative humidity sensors showed excellent correlation with SCAQMD Met Station sensors: temperature R2 >0.91 and relative humidity R2 >0.94

The 千部毛片免费观看_美女网站免费视频 AQY 1 is the best instrument I’ve seen for non-professionals seeking a serious air pollution measurement capability, since the device measures three different pollutants: particulate matter, ozone, and nitrogen dioxide (as well as temperature and dew point).Dr Jeff Masters, Weather Underground
