Drone-Based Air pollutant



Geo-4D use the Sniffer-4D to offer high precision 3D airborne pollutant mapping. The Sniffer-4D uses eight precision onboard Alphasense gas sensors, along with temperature, pressure and humidity sensors to detect various airborne pollutants simultaneously: VOCs, CH4, NO2, O3, CO, SO2, PM1.0, PM2.5 and PM10.

The Sniffer-4D is a compact unit that can be drone or vehicle mounted to allow for real-time data capture at various elevations.


When mounted on a drone, the terrain beneath the flight path can be simultaneously 3D mapped whilst air pollutant data is being acquired.


Whether you need to better characterise pollution levels for health advice, mapping of leaks, monitoring purposes, or for your own R&D, we can help you.
