Summary

TOP PERFORMANCE IN NO2 MEASUREMENT

 

With immense joy, we are thrilled to share the outstanding achievements of our WT1 device in the recent AIRLAB 2023 International Microsensors Challenge organized by AIRPARIF!

The WT1 outshone its competitors by achieving the “best performance” accolade, notably in the NO2 measurement (Lille site in France), and earned the distinguished qualification of “excellent quality” under real-world test conditions.

We take great pride in the versatility and reliability demonstrated by the WT1, which also exhibited remarkable proficiency in measuring PM1, PM2.5, and O3. The WT1’s capability to furnish a comprehensive list of targeted pollutants, providing a thorough understanding of air quality, was also commended by the esteemed jury.

The jury particularly appreciated the advanced features of the WT1, including comprehensive data retrieval options, real-time notifications, and user-friendly configuration, further solidifying its performance.

A heartfelt thank you extends to the entire internal team at ELLONA whose dedicated efforts contributed significantly to today’s success of the WT1, and to our clients who have faithfully followed and trusted us throughout the years. Let’s continue our collective journey of pushing the boundaries of innovation for even more effective environmental emissions monitoring!

Special gratitude goes to the entire team at AIRPARIF for their impeccable organization of this significant event.

Mark your calendars as the next edition of the AIRLAB challenge is set to take place in 2025.

The 4th Edition of the Challenge

Airparif initiated a study aimed at assessing the impact of new parameters on the performance of microsensors, with a particular focus on:

  • Elevated pollution levels
  • Different emission profiles
  • Varied meteorological conditions, including notably higher temperatures and humidity.

Performance tests were conducted in France, as in previous editions, but with a new addition this time: for the first time, tests were also carried out abroad, in Bangkok, Thailand. Airparif supervised the entire testing process, while outdoor air trials in France were conducted by Atmo Hauts-de-France in Lille.

The 2023 edition of the AIRLAB Microsensors Challenge received support from the Clean Air Fund, the French Development Agency (AFD), the Agency for Ecological Transition (ADEME), Bloomberg Philanthropies, and the French Embassy in Thailand, as part of the Franco-Thai Innovation Year.

In collaboration with the Asian Institute of Technology, Atmo France, Atmo Hauts-de-France, the Bangkok Metropolitan Administration, the Scientific and Technical Center of the Building / Observatory of Indoor Air Quality, EMPA, FIMEA, the National Institute of Metrology Thailand, UN-ESCAP, and the World Meteorological Organization (WMO).
