Air Quality Sensor (AX500)
Rugged Air Quality Sensor
The Geolux AX500 (powered by SmartSense) is a rugged, multi-parameter air quality sensor designed to accurately monitor key atmospheric gases (NO, NO₂, CO, SO₂, and O₃) along with particulate matter (PM1, PM2.5, and PM10). Built for harsh environments, it features an automatic self-cleaning system, low-power operation, and multiple communication interfaces for seamless integration with environmental monitoring systems.
