Whether you are looking for a home deployment or a larger scale, the AirGradient ONE is certified and ready to perform.
Optimised enclosure
The enclosure has been designed with two primary goals: first, to ensure accurate measurements of the air quality and second, to be robust and long-lasting. For accurate measurements, it is important that there is good airflow to the sensor modules, that air loops in front of the sensor modules are avoided, and that the risk of condensation inside the enclosure is reduced as much as possible. The enclosure is very robust and made of high-quality ASA plastic, providing excellent durability and UV protection.
