The M20 radiosonde is the most environmentally friendly radiosonde available on the market.

This small instrument used worldwide has the lowest environmental impact, enables efficient measurements and provides reliable data thanks to its multi-constellation GNSS (as of 2018), even in harsh environments.

If you're looking to reduce your carbon footprint while ensuring relevant data at an affordable price, choose the M20, the radiosonde that makes a difference in the field.

Meteomodem recently received ISO 14001 certification, reinforcing the commitment of our team to continue working to develop sustainable and reliable solutions.

Over the past 20 years, Meteomodem has reduced the amount of polystyrene in its instruments by a factor of 12, the weight of electronics by 3 and the weight of batteries by 6. The M20 is the culmination of a long-term technological vision.

The M20 is a must-have, the lightest, smallest and most cost-effective radiosonde.
