GROUPE TERA

Groupe TERA is an SME founded in 2001 that employed 103 people at the end of June 2025. Groupe TERA is a leader in real-time air quality measurement and assessment. The Group relies on two complementary and synergistic activities: the design, development, and marketing of innovative “Made in France” sensors and a digital offering consisting of innovative professional analysis software capable of processing air quality data collected by the sensors. This latter solution is complemented by its individual citizen sensor.

Sensors for real-time measurement of environmental parameters
- Ambient air, outdoor air, environment
- Critical environments: microelectronics, space, etc.
- Health: hospitals, etc.

The NextPM sensor is a next-generation solution for air quality monitoring, delivering real-time PM1, PM2.5, and PM10 measurements in µg/m³ and pcs/L. Thanks to its patented airflow control and humidity management technology, it provides highly accurate and stable particulate matter data, even in challenging environments with high humidity or pollution. With minimal maintenance and a lifetime of up to 10 years, NextPM is ideal for smart city networks, industrial monitoring, and environmental applications.
