Airyx WGA020 Abwasser-Gas-Analysator

Hochpräzise N₂O-, CH₄- und CO₂-Emissionsüberwachung und O₂‑Kontrolle für Klärwerke.

English Product Page

Höchste Präzision – Verlässliche Daten

Der Airyx WGA020 Abwasser-Gas-Analysator ermöglicht eine hochpräzise Echtzeit‑Überwachung von N₂O, CH₄, CO₂ und O₂ in belüfteten Becken und berechnet automatisch Netto‑Emissionsraten für Prozess‑ und Klimaberichte.

Das System wurde für das langfristige Treibhausgas‑Monitoring in Kläranlagen entwickelt und entnimmt die Proben direkt oberhalb der Wasseroberfläche mittels schwimmender Haube. Der Analysator misst kontinuierlich N₂O, CH₄, CO₂ und O₂ und ermittelt die Netto‑Gasflüsse über einen integrierten Volumenstromsensor.

Eine Probenlufttrocknung, automatische Querempfindlichkeits‑Korrekturen sowie ein temperaturstabilisiertes Sensorgehäuse gewährleisten einen stabilen, driftarmen Betrieb auch bei wechselnden Umweltbedingungen.

Praxisgerechtes Design für Kläranlagen

Das robuste IP64‑Gehäuse ist für den dauerhaften Außeneinsatz ausgelegt. Es sind keine fest angeschlossenen Kalibriergasflaschen erforderlich – das reduziert Betriebsaufwand und Kosten.

Bedienung und Datenzugriff erfolgen über das Front‑Touchdisplay oder eine browserbasierte Weboberfläche via LAN. Optional ermöglicht eine LTE‑Anbindung den sicheren Fernzugriff für Monitoring und Service.

Welche Gase misst der WGA020?

Der Abwasser-Gas-Analysator Airyx WGA020 ermöglicht gleichzeitige Messungen von N₂O, CH₄, CO₂ und O₂ für ein vollständiges Emissionsprofil von Abwasseranlagen.

Welches Messprinzip wird verwendet?

Der Analysator nutzt das NDIR‑Messprinzip für N₂O, CO₂ und CH₄, während O₂ über einen elektrochemischen Sensor erfasst wird.

Benötigt der Analysator Kalibriergasflaschen?

Es ist kein kontinuierliches Kalibriergas erforderlich; lediglich eine jährliche Sensorkalibrierung mit Standardgas ist notwendig.

Wird das System durch wechselnde Umgebungstemperaturen beeinflusst?

Der WGA020 arbeitet zuverlässig im Temperaturbereich von −10 °C bis +40 °C dank temperaturstabilisierter interner Komponenten.

Wie häufig ist eine Wartung erforderlich?

Die jährliche Wartung umfasst die Sensorkalibrierung, den Austausch des Scrubbers sowie die Reinigung der Probenahmehaube.

Kann das System mehr als eine Haube überwachen?

Ja, der Dual‑Hauben‑Betrieb ermöglicht die Überprüfung räumlicher Variabilität sowie quasi‑gleichzeitige Messungen.

Wie werden die Emissionen erfasst?

Eine schwimmende Probenahmehaube sammelt das Gas direkt oberhalb der Wasseroberfläche für eine stabile und repräsentative Probenahme.

Wie erfolgt der Datenzugriff?

Über das Touch‑Display, das Web‑Interface, Ethernet oder optional über ein LTE‑Modem für den VPN‑Fernzugriff.

Was die Beispieldaten zeigen

Beispieldaten veranschaulichen typische tägliche Muster von Treibhausgasemissionen in Belebungsbecken. CO₂ und N₂O zeigen ausgeprägte tageszeitliche Spitzen, die durch biologische Aktivität, Belüftungsintensität und Beckenbelastung bestimmt werden. Aufgrund des sehr hohen Treibhauspotenzials von N₂O führen bereits geringe Konzentrationsänderungen zu einer starken Klimawirkung. Der WGA020 löst diese Dynamiken in Echtzeit auf und unterstützt Betreiber dabei, Emissions‑Hotspots zu identifizieren, die Belüftung zu optimieren und Netto‑Emissionsflüsse für Berichterstattung und Prozesssteuerung zu quantifizieren.

Fazit

Zusammenfassend bietet der WGA020 zuverlässige Echtzeit‑Messungen von Treibhausgasen für moderne Abwasseranlagen. Die Kombination aus der Überwachung von N₂O, CH₄, CO₂ und O₂, dem robusten Außendesign sowie automatisierten Korrekturroutinen macht ihn zu einer verlässlichen Langzeitlösung für die operative Prozessoptimierung, die regulatorische Berichterstattung und wissenschaftliche Anwendungen.

OPEN PATH COMPACT HYBRID INSTRUMENT

Airyx Admin — Mon, 24 Nov 2025 14:30:26 +0000

Airyx OPC‑VIS‑LED‑300 Hybrid Open Path DOAS Instrument

PRECISE OPEN-PATH AND VERTICAL MAX-DOAS MEASUREMENTS FOR ADVANCED GAS AND AEROSOL MONITORING.

Description

This section provides an overview of the hybrid open‑path and MAX‑DOAS concept used by the OPC‑VIS‑LED‑300.

Hybrid DOAS concept

The Airyx OPC‑VIS‑LED‑300 is a hybrid open path DOAS instrument. It combines active open‑path DOAS and passive MAX‑DOAS in one compact system. As a result, it supports long‑path concentration measurements and vertical profiling in a single device.

Multi‑path open‑path mode

In active mode, a 450 nm LED and retroreflectors create a defined optical path for NO₂ and Glyoxal measurements. Meanwhile, the motorized UV telescope can switch between several reflectors, enabling tomography, fence‑line monitoring and spatial coverage without manual alignment.

Passive MAX‑DOAS mode

In passive mode, the instrument retrieves vertical profiles of NO₂, H₂O, Glyoxal, HCHO, HONO, O₃, O₄, SO₂, IO, BrO and OClO. Therefore, it supports a wide range of atmospheric and air‑quality applications.

A temperature‑stabilized spectrometer (300–550 nm, FWHM < 0.5 nm) ensures precise spectral data. In addition, the stable optical design supports accurate retrievals in both active and passive operation.

Thanks to its IP64 housing and internal heating, the OPC‑VIS‑LED‑300 performs reliably in demanding outdoor environments. Consequently, it is suitable for both short‑term campaigns and long‑term monitoring. Moreover, combining two measurement modes in one instrument reduces equipment complexity in the field.

System Overview

The image illustrates the main components and beam geometry of the hybrid open‑path and MAX‑DOAS setup.

Key Features

The hybrid open path DOAS design provides accurate long‑path gas measurements and multi‑species retrievals from a single compact setup.

Accurate gas detection

Active open‑path DOAS detects NO₂ and Glyoxal with proven optical stability. Long‑path remote sensing avoids losses in sampling lines and improves accuracy under varying atmospheric conditions.

Vertical profiles via MAX‑DOAS

Passive MAX‑DOAS retrievals deliver vertical profiles of NO₂, H₂O, Glyoxal, HCHO, HONO, O₃, O₄, SO₂, IO, BrO and OClO. This supports detailed boundary‑layer and atmospheric chemistry studies.

Compact and flexible hybrid design

Active and passive DOAS measurements are integrated in one compact unit. As a result, the system reduces logistical complexity during field deployments and survey campaigns.

Rugged and mobile

An IP64 housing with internal heating and dew‑point monitoring ensures stable performance in outdoor environments. Optional battery operation increases mobility for remote sites.

Plug‑and‑play setup

The motorized telescope allows automatic self‑alignment. Consequently, the instrument can be deployed quickly and used for tomography or fence‑line monitoring with minimal effort.

Calibration‑free operation

DOAS technology does not require calibration gases and shows no significant long‑term drift. Therefore, operating costs remain low even during extended measurement periods.

Applications

The OPC‑VIS‑LED‑300 hybrid analyzer supports both open‑path and vertical profiling applications. Therefore, it is suitable for a wide range of atmospheric and industrial monitoring tasks. As a result, users can answer several atmospheric questions with only one instrument.

Air‑quality monitoring and workplace exposure analysis
Industrial emission oversight and process control
Satellite validation near the surface (MAX‑DOAS)
Boundary‑layer chemistry and aerosol optical property studies
Fence‑line monitoring at industrial or agricultural sites
Tomographic spatial distribution analysis using multiple reflectors

In addition, the system design simplifies field handling and reduces deployment time. This makes the OPC‑VIS‑LED‑300 a flexible solution for both temporary campaigns and fixed monitoring stations.

Frequently Asked Questions

What measurement techniques does the OPC‑VIS‑LED‑300 use?

The instrument combines active open‑path DOAS using a 450 nm LED with passive MAX‑DOAS. This hybrid approach enables both long‑path concentration measurements and vertical profile retrievals.

Which gases can be detected in active open‑path mode?

In active mode, the OPC‑VIS‑LED‑300 detects NO₂ and Glyoxal along a defined optical path between the telescope and a retroreflector.

Which species are available in MAX‑DOAS mode?

Passive MAX‑DOAS retrievals provide information on NO₂, H₂O, Glyoxal, HCHO, HONO, O₃, O₄, SO₂, IO, BrO and OClO, as well as aerosol optical properties. Therefore, the system supports a broad range of atmospheric studies.

What typical path lengths are possible?

Open‑path measurements can be performed over distances of up to 1000 m. The achievable range depends on visibility, reflector configuration and integration time.

Does the instrument require calibration gases?

No. DOAS measurements are inherently calibration‑free and do not require calibration gas cylinders. This significantly simplifies operation and reduces long‑term costs.

High precision – Reliable data

The Airyx WGA020 wastewater gas analyser provides high‑precision, real‑time monitoring of N₂O, CH₄, CO₂ and O₂ in aerated basins and automatically calculates net emission rates for process and climate reporting.

Designed for long‑term greenhouse‑gas monitoring in wastewater treatment plants, the system samples directly above the water surface using a floating hood. In addition, the analyser measures N₂O, CH₄, CO₂ and O₂ in real time and derives net fluxes through an integrated total‑flow sensor.

Moreover, sample‑air drying, automatic cross‑interference correction and a temperature‑stabilised sensor housing ensure stable, low‑drift performance under changing environmental conditions.

Field‑Ready Design for Wastewater Environments

Additionally, the rugged IP64 enclosure supports continuous outdoor operation. The system requires no permanently attached calibration gas bottles, which reduces operating effort and cost.

Instrument control and data access are available via the front‑panel touch display or browser‑based web interface over LAN. Furthermore, optional LTE connectivity enables secure remote access for monitoring and troubleshooting.

What the example data shows

Exemplary data illustrates typical daily patterns of greenhouse gas emissions in aerated wastewater basins. CO₂ and N₂O exhibit clear diurnal peaks driven by biological activity, aeration intensity and basin loading. Because N₂O has a very high global warming potential, even small concentration changes translate into strong climate impact. The WGA020 resolves these dynamics in real time, helping operators identify emission hotspots, optimize aeration and quantify net emission fluxes for reporting and process control.

Conclusion

In summary, the WGA020 provides reliable real‑time greenhouse‑gas measurements for modern wastewater facilities. Its combination of N₂O, CH₄, CO₂ and O₂ monitoring, robust outdoor design and automated correction routines makes it a reliable long-term solution for operational optimisation, regulatory reporting and research applications.

The ICAD‑HONO/NO₂‑210L provides fast, direct and calibration‑free measurements of nitrous acid (HONO) and nitrogen dioxide (NO₂) using high‑resolution Iterative Cavity DOAS spectroscopy. The method quantifies both gases purely spectroscopically, without converters, reagent gases or external calibration standards.

The long effective absorption paths of the optical resonator enable sub‑ppb detection limits with 1‑second time resolution. Because the measurement is fully optical, the system shows no significant cross‑sensitivities, no humidity‑related artefacts and requires no sample drying. Integrated zero checks and temperature‑stabilised optics ensure long‑term stability with minimal maintenance effort.

With low power consumption and a compact 19″ rack design, the analyzer is suited for laboratory studies, stationary air‑quality monitoring and mobile field campaigns on vehicles or ships. A browser‑based graphical interface provides full access to data, system diagnostics and configuration via Wi‑Fi or LAN.

Operation Principle

The analyzer uses a closed‑path optical resonator that provides effective absorption paths up to 3 km. HONO and NO₂ concentrations are derived from Iterative Cavity DOAS (ICAD) spectroscopy in the 350–390 nm wavelength range.

The measurement is fully spectroscopic and direct. No converters, reagent gases or sample drying are required. Automatic zero checks and temperature‑stabilised optics ensure low drift and reliable operation under laboratory and field conditions.

ICAD IN SITU NOx INSTRUMENTS

Airyx Admin — Wed, 06 May 2020 13:04:42 +0000

ICAD NO₂–NOx–NO Analyzer Series 210

The ICAD Series 210 provides precise and fast in‑situ measurements of NO and NO₂ using patented Iterative Cavity DOAS spectroscopy. It directly detects NO₂ — without converter artefacts and without humidity interferences — and operates without the need for NO₂ calibration gas.

ICAD instruments offer very low noise, negligible zero drift and a wide dynamic range. This makes them suitable for both highly polluted roadside environments and ultra‑clean background locations. Thanks to low power demand and robust housings, ICAD systems can be used in stationary installations, industrial stacks, mobile vehicle platforms, ships and UAV‑based deployments.

Models equipped with integrated CO₂ sensors (DE versions) support real‑time plume chasing and NOx emission‑factor calculations for on‑road and off‑road applications.

Operation Principle

The ICAD analyzer uses a closed‑path optical resonator to achieve very long effective absorption paths. This enables highly sensitive detection of NO₂ based on its characteristic absorption features in the 430–480 nm wavelength range.

NO is measured via an internal ozone‑based, NOx‑free converter that converts NO to NO₂. Two parallel measurement cells — one for direct NO₂ and one for NO after conversion — ensure precise and drift‑free NO, NO₂ and total NOx quantification. The method is insensitive to humidity and requires no sample drying.

SKYSPEC INSTRUMENTS

SKYSPEC INSTRUMENTS RECORD ULTRA-VIOLET AND VISIBLE SPECTRA OF DIRECT SUN AND SCATTERED SKYLIGHT, FOR REMOTE DETECTION OF ATMOSPHERIC TRACE GASES (E.G. NO₂, SO₂, HCHO, O₃, H₂O) AND AEROSOLS.

THE MOTORIZED TELESCOPE UNIT WITH ELEVATION CORRECTION ENABLES AUTOMATIC DATA ACQUISITION AT CUSTOM VIEWING ANGLES. THE TEMPERATURE STABILISED SPECTROMETER WITH SUB-NM RESOLUTION IS OPTIMISED FOR ACCURATE DETECTION OF TRACE GAS ABSORPTION FEATURES.

COMBINED WITH OUR EVALUATION SOFTWARE PACKAGE, SKYSPEC INSTRUMENTS PROVIDE DIFFERENTIAL COLUMN DENSITIES OF GASES (dSCD), VERTICAL COLUMN DENSITIES (VCD) AND NEAR SURFACE CONCENTRATIONS (NSC). USERS CAN EVEN WITH THEIR OWN PROFILING ALGORITHMS DERIVE VERTICAL CONCENTRATION PROFILES OF TRACE GASES AND AEROSOLS.
