🌍 Introducing the All-New SKYSPEC v.260 — Pre 🌍 Introducing the All-New SKYSPEC v.260 — Precision, Reimagined 🚀
We're proud to announce the official release of the SKYSPEC v.260, the latest generation of our cutting-edge passive remote sensing instrument — now faster, more compact, and more capable than ever before.
💡 What’s New in v.260?
✅ Increased Motor Speed – A new elevation stepper motor delivers faster repositioning across elevation angles, minimizing delay between scans and boosting efficiency in dynamic environments.
✅ Enhanced Elevation Correction – With real-time automatic tilt correction, v.260 offers smoother, more accurate operation — especially valuable for mobile deployments on ships or vehicles.
✅ More Compact Design – Featuring a shortened telescope glass tube, SKYSPEC v.260 packs the same analytical power into a smaller, more portable form — ideal for fieldwork, mobile labs, and tight installations.
🔬 Built for Atmospheric Insight
SKYSPEC systems use the Differential Optical Absorption Spectroscopy (DOAS) method to detect a wide range of gases (e.g., NO₂, SO₂, HCHO, BrO, H₂O) and aerosol properties by analyzing scattered skylight and direct sunlight. With high spectral resolution, temperature-stabilized spectrometers, and customizable modular setups, SKYSPEC enables high-precision atmospheric research in diverse environments — from remote field stations to urban monitoring vehicles.
🌐 Applications Include:
• Regional Air Quality Monitoring
• Mobile Emission Surveys
• Satellite Data Validation
• Volcanic & Industrial Plume Analysis
• Gas Imaging with Real-Time Overlays
🧩 Modular, Rugged, and Ready to Deploy
Whether you're building a stationary monitoring station or a mobile sensing platform, SKYSPEC v.260 is engineered for performance, reliability, and adaptability.

📝 "Identification of High Emitting Heavy-Duty V 📝 "Identification of High Emitting Heavy-Duty Vehicles Using Plume Chasing: European Case Study for Enforcement" by Schmidt et al. 2025

📢 Our peer-reviewed paper is now published and freely available!
🔗 Read it here: https://www.sciencedirect.com/science/article/pii/S0048969725014858
This is our publication and our technology — showcasing the real-world performance of our Plume Chasing measurement system, developed specifically for on-road emission detection of heavy-duty vehicles (HDVs).
🚛💨 Our system was used in multiple European countries between 2016 and 2023, measuring nearly 5,000 HDVs for NOx, with solid particle number (PN) and black carbon (BC) emissions measured for over 1100 vehicles.
🛠️ Key capabilities of our Plume Chasing solution:
Real-time, on-road emission measurements
Automatic classification of suspect and high emitters within seconds
Seamless support for on-site enforcement actions
Proven accuracy and reliability, confirmed through vehicle inspections by authorities
📊 Proven impact:
In Czechia and Slovakia Plume Chasing flagged up to 41% of HDVs as high emitters.
Follow-up inspections revealed tampering, defects, or malfunctioning emission systems.
Just 4–14% of the worst vehicles cause over 50% of particle pollution in HDV fleets.
Countries with strong enforcement and regular use of our technology (like Denmark) showed dramatic improvements in fleet cleanliness.
🚓💡 The message is clear:
Our Plume Chasing system enables fast, efficient, and targeted emissions enforcement. Authorities can use the Airyx Plume Chasing system to act on data in real time — identifying the worst polluters on the spot, without the need for expensive lab testing or random stops.
📣 We encourage environmental agencies, transport ministries, and enforcement bodies across Europe and beyond to implement this powerful tool. The technology is ready, proven, and making a measurable difference.

🌍 Waste Gas Analyzer for N₂O and CH₄ Emissi 🌍 Waste Gas Analyzer for N₂O and CH₄ Emissions – A Breakthrough by Airyx 🌱
Airyx has successfully applied its newly developed gas analyzer to measure greenhouse gas emissions from wastewater treatment plants! The analyzer monitors the climate gases nitrous oxide (N₂O) and methane (CH₄), as well as system parameters carbon dioxide (CO₂) and oxygen (O₂). Additionally, it converts the concentrations to emission fluxes.
👉 Application Area:
The gas analyzer is applied at denitrification basins to monitor greenhouse gas emissions and to support the development of effective mitigation measures. Airyx has patented this innovative measurement technology specifically for this application.
👉 Successful Testing Phase:
The system was tested over six months at the wastewater treatment plant in Mannheim, delivering continuous and robust data for wastewater treatment plant operations. The measurements are currently being analyzed alongside operational parameters to develop strategies for reducing greenhouse gas emissions.
👉 Future Prospects:
Based on the experience gathered in the field, Airyx is now working on an improved analyzer, which will soon be available to other customers.
With this achievement, Airyx is making a significant contribution to climate protection and the sustainable optimization of wastewater treatment plants! 🌟

🌟 Happy to announce! 🌟 The Airyx Study in Sl 🌟 Happy to announce! 🌟
The Airyx Study in Slovakia has been officially published as part of the ICCT and TRUE initiative, in cooperation with TU Graz. 🚗🔬
Our team conducted emission measurements of vehicles focusing on NOx and particles, using the advanced Airyx Plume Chasing System.
One of the key highlights of the study was identifying high-emitting trucks, often due to illegal manipulation or defects. 🚛💨
The results are alarming: A significant number of trucks exceed acceptable emission levels. 🚨 Inspecting these vehicles, police have uncovered cases of manipulation and mechanical defects that cause excessive pollution.
We hope that police and traffic authorities will adopt our emission measurement systems to identify high emitters and enforce fines where necessary. Together, we can make our air cleaner! 🌍💪
