Wildfire & Indoor
Wildfire smoke protection, indoor air quality certification, brownfield remediation, and community monitoring.
Hot-Swap Sensor Head Technology
The same Aeroqual sensor heads work across Ranger and Series 500 platforms — change in seconds, no tools, no recalibration. One sensor head fleet covers multiple monitors on site.
Sensor Heads
Modular Air Quality Sensor Heads
Aeroqual's swappable sensor heads cover PM and 13+ gas pollutant types. Built with Gas Sensitive Semiconductor (GSS), Gas Sensitive Electrochemical (GSE), and optical PMX particle counter technology — all with active fan sampling for accurate, defensible data.
About Aeroqual Sensor Heads
Swap in seconds. No recalibration required.
Aeroqual sensor heads plug into the Ranger and Series 500 monitor base — hot-swappable in the field with no configuration or recalibration required. Each head carries its calibration data onboard.
Sensor technology includes Gas Sensitive Semiconductor (GSS) and Gas Sensitive Electrochemical (GSE) designs, plus the optical PMX particle counter head for simultaneous PM1/PM2.5/PM4/PM10/TSP. Active fan sampling on all heads ensures highly accurate, consistently reproducible measurements.
