Featuring outstanding flexibility, The Aeres-XL is a fixed all-in-one UV-DOAS solution for the most complex stack or process monitoring challenges. With the ability to choose from a range of fiber coupled cells, custom cross process adapters, and insitu mono-static probes, it is ideal for continuous emissions monitoring (CEMs) applications, laboratory setups, closed cell process monitoring, and insitu process monitoring. It comes packaged in a NEMA4 rated enclosure for outdoor environments, or a 19 inch rack mount enclosure for indoor. Like our other UV-DOAS solutions, these analyzers accurately detect gases from part-per-billion (ppb) level to percent level concentrations and report the data in real-time.
The Aeres-XL is an analyzer recognized for it’s accuracy in measuring Ammonia (NH3), Chlorine (CL2), Sulfur Dioxide (SO2), and BTEX, as well as handling challenges with industrial hygiene, leak detection, environment contamination & remediation, and more. Despite the advanced detection system employed in the Aeres-XL, accurate results can be achieved out of the box with a flip of a switch. Automatic operating happens inside the device – no “lab expert” knowledge is required.

How it Works
Point UV-DOAS Technology
The Cerex UV Hound operates using a process known as point monitoring in an enclosure connected to a stack via a probe. Surrounding ambient gases are channeled into the analyzer via the probe. Following this, an internal cell holds the gas sample for analysis.
Next, with UV-DOAS technology, an ultraviolet light passes through the gas sample contained within the cell. Thanks to a physics principle known as the Beer-Lambert Law and Cerex’s proprietary software, the gas sample can be translated into useable data.
Similar to more expensive FTIR technology, UV-DOAS offers better detection limits at lower cost without interference from water vapor. Within seconds, any compounds present in the internal cell that are UV spectrum-detectable are identified and quantified according to their absorption from the ultraviolet light. Cerex’s Continuous Monitoring Software (CMS) outputs the data in real-time for instant results. Raw data can be accessed either on the Cerex Aeres itself, or remotely via phone, tablet, or computer.
The most cost-effective sampling & detection solution
Offering real time identification and quantification of criteria pollutants, the Aeres analyzers provide sensitive yet cost-effective solution in one easy to operate, all-in-one package – saving thousands of dollars as opposed to expensive, separate laboratory analysis.
Individual species of prolific hazardous air pollutants
Toxins such as Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) are known human carcinogens at ambient air levels. Our Aeres analyzers are capable of simultaneously detecting these in addition to oxides of Nitrogen (NOx), CAFO emissions such as Ammonia (NH3) and Hydrogen Sulfide (H2S), and other volatile organic compounds (VOC’s) below hazardous levels.
Low maintenance and low detection limits
With only 3 consumables and the capability of simultaneous, single digit, parts-per-billion (ppb) detection levels of multiple compounds, the Aeres is standard for ambient level detection.
Common Detectable Gases
Ultra Low Detection Limits
The Cerex Aeres has as low as parts-per-billion minimum detection limits and wide dynamic ranges, allowing earlier and more thorough detection of gases than traditional sensor arrays. In comparison to outdated technologies, Aeres analyzers feature multi-gas monitoring of individual species, lower detection limits, no water vapor interference, inherent calibration and no sensors to poison.
The analyzer may calibrated insitu using calibration gas delivered from a dynamic calibrator or cylinder standard. Routine calibration is unnecessary for proper operation.
Targeted Library for Increased Value and Cost-Effectiveness
Cerex Aeres analyzers include one multi-purpose standard library suitable for monitoring of 23 compounds. Custom calibrations are available based on application. Additionally, ancillary sensors can be added to the Aeres for detection of other gases not available with UV-DOAS, such as Carbon Dioxide, Carbon Monoxide, Methane, and more.
Aeres Common Target Gases
|1,3 Butadiene C4H6|
|Carbon Disulfide CS2|
|Chlorine Dioxide ClO2|
|Ethyl Benzene C8H10|
|Hydrogen Sulfide H2S|
|Nitric Oxide NO|
|Nitrogen Dioxide N2O|
|Nitrous Acid HNO2|
|Sulfur Dioxide SO2|
|O-Xylene, M-Xylene, P-Xylene C8H10|
*NOTE: For detection of gaseous compounds not available within the UV spectrum, we recommend the Cerex FT-5000 Series. These analyzers use FTIR (Fourier Transform Infrared) that will be perfect for your stack, process or zone monitoring applications.
Results You Can Rely On
Cerex recognizes that detailed gas monitoring results need to be reliable and available quickly to various stakeholders. Consequently, Cerex engineers developed software to accurately detect and display gases within the air, in real-time, from any location.
On a Cerex Aeres, a user can see results on the analyzer itself, or remotely via a phone, tablet, or computer anywhere in the world via a virtual connection. GPS and cellular configurations make this possible in isolated environments.
All data is automatically saved in an easy to access .csv file; this feature helps our clients in various ways - from daily use to crucial events such as evidence in court. Early detection translates into quicker response times, reduced environmental impact, decreased plant downtime, and reduced exposure to site personnel and the community.
Real time spectral subtraction and synthetic background implementation allow the UV Hound and Micro Hound to clearly display accurate concentrations of target gases over 1000 meters without interference from other gas species
Serving clients in a variety of industries
The Cerex Aeres is a fantastic solution for when minimum detection limits must be lower than possible for FTIR, when water vapor can cause interference and key UV-detectable compounds need to be detected within a stack (including Ammonia, Carbon Disulfide, and more).
Hound series analyzers may also be used for portable stack analysis of Ammonia (NH3), Nitric Oxide (NO), Nitrogen Dioxide (NO2), Sulfide Dioxide (SO2), and some volitive organic compounds (VOCS) if installed downstream of a sample conditioning system providing a cool, dry sample. A dilution system may also be required when measuring high parts-per-million (ppm) levels of combustion gases.
The FR options are well suited for smoky or dusty environments with a faster sample rate and replaceable glass fiber sub-micron sample filter.
