CleanAir Engineering—the authority on air quality monitoring. Let us introduce you to one of our favorite ambient air monitoring product lines from Aeroqual.

Used in over 70 countries, processing more than 6 million measurements a day, Aeroqual instruments deliver the best balance of function, portability, and affordability on the market today. Aeroqual is quickly becoming one of the most trusted names in environmental air quality monitoring. Evidence of their success includes their recent collaborative partnership with the EPA to develop lower-cost monitoring solutions and their six active sensor patents, alongside product environmental agency certifications.

Pair these fenceline, portable, and handheld sampler products with world-class service and support from CleanAir and empower your team with the defensible data your organization demands—accurate, immediate, and actionable. Measure PM 2.5, smoke, BTEX, VOC’s and more.

AirNow Air Quality Interactive Map ScreenshotAs public interest in air quality continues to rise, new companies continue to crop up in the low-cost monitor market: Atmotube, Awair, IQair, and PurpleAir, just to name a few. Citizen scientists are looking for cost-effective options for collecting reliable data, but the real question is “How do you know your numbers are accurate?”

To determine the AQI, AirNow and the EPA rely on highly-specialized meters and sensors capable of measuring at FRM/FEM (Federal Reference Method/Federal Equivalent Method) standards that require careful and regular cleaning or calibration. Developing a maintenance schedule and on-going budget for your analyzer network ought to be a part of every ambient monitor purchase. Don’t expect that monitor you deployed three years ago to still churn out accurate data.

Data disparities between low-cost, consumer-accessible monitors and Federal BAM equipment are widely known within the air monitoring industry. Some studies report that data from some increasingly-popular “no reference” monitors are inaccurate by as much as 36-48%! This class of monitors is considered to be “indicative”, educational, or informational, as opposed to “Reference” analyzers relied on by regulatory agencies or the “Near Reference” systems manufactured by Aeroqual. Indicative-Class monitors must rely on correction factors and complex calculations to scrub data in order to simulate Reference sample data. Why not start with testing equipment better suited to collecting actionable, reliable data?

Web-Enabled Data Monitoring. Aeroqual products purchased or rented from CleanAir come available with cloud-based services. Highly customizable, Aeroqual or CleanAir portals are capable of amalgamating and analyzing complex data and can even alert monitoring professionals when site conditions change. Whatever your site contribution needs, CleanAir can help you meet them: ambient networks, pollution modeling, instrument siting,

  • Never lose data due to cell service failure. Missing data is logged and uploaded.
  • Site contribution
  • Heat index calculations
  • Highly-Customizable alarms using real-time data

Near Reference Data Fidelity. Manufacturing sensors in-house has its benefits. Being an expert in sensor design and production means that Aeroqual can achieve a targeted blend of cost-effectiveness, hardware robustness, and data accuracy. Minimizing sensor drift by compensating for field conditions are all a part of Aeroqual’s commitment to manufacturing world-class equipment. Near Reference instrumentation allows organizations and businesses to fully comply with government regulations such as DER-10 New York, Rule 1466 California, and federal EPA guidelines. Have questions about Near Reference?

Factory and Field Calibration. CleanAir verifies each and every factory-calibrated Aeroqual unit before shipping it to customers, taking our level of service one step further. Routinely calibrating any environmental air monitoring product is essential to delivering the defensible data our industries expect.

Tough Enclosures. AQM and AQS monitors feature IP65-rated weatherproof housing, improving unit longevity and data accuracy. The AQM utilizes Aeroqual’s integrated Thermal Management System which regulates internal air temperature and relative humidity.

Advanced Monitoring Applications

Testing Capabilities

A broad Aeroqual product line provides environmental air professionals with a wide range of testing capabilities in a wide range of applications. Analyzers can be effectively deployed to measure outdoor air quality and indoor ambient conditions at construction and remediation sites, schools or higher education facilities, vehicle emissions testing facilities, wildfire clean-up or ash removal sites, and more. Dust, ash, smoke, and other airborne particulates can be measured by any Aeroqual monitor.

Aeroqual’s unique approach to hardware design focuses on customer easy-of-use and customizability. AQM65 and AQS1 modular base units can be adapted to meet the unique monitoring needs of customers in a broad variety of industries. AQM enclosures are large enough to accommodate BTEX (Benzene, Toluene, Ethylbenzene and Xylene) monitoring components or up to 20 different environmental parameters simultaneously1. AQS1 enclosures can accommodate particulate monitoring and up to three gases of interest simultaneously2. Dust Sentry dust monitors utilize the same enclosure as the AQS1, but are designed for particulate measurement. Handheld Series 500 (S-500) units feature a wide range of swappable sensor modules, allowing users to monitor environmental parameters one at a time. Five available modules can measure 15 criterion.

Available Accessories

Each Aeroqual instrument is compatible with a variety of accessories to help you meet your organization’s air quality monitoring needs. AQM units take advantage of the greatest number of accessories and components, with many accessory modules also compatible with AQS systems. The smaller S-500 handheld form factor provides operators with a balanced compromise between portability and data depth. Some of the most popular accessories allow users to customize their instruments to meet changing demands in ambient air monitoring.
