Nubo Sphere's performance in ADED 2023 | Version 2; the latest advancements in continuous methane emissions monitoring

Our Nubo Sphere continuous methane monitoring solution was put to the test at the Advancing Development of Emissions Detection (ADED) campaign of 2023, a blind controlled-release testing campaign organized by the Methane Technology Evaluation Center (METEC), of Colorado State University (CSU). In last year’s ADED campaign, Nubo Sphere used a common metal oxide (MOx) sensor to measure ppm concentration of methane in the air. It showed great performance compared to other technologies and solutions.
