|
| |
|
|
The AX-AQM-3-M is an ideal solution for detecting harmful emissions in parking garages, loading docks, warehouses etc. It offers the detection of carbon monoxide, nitrogen dioxide gases and Particulate matter in the same enclosure. The NO2 and CO sensor modules use plug-in connectors, making easy in-the-field replacement easy. PM2.5/10 sensor uses the laser light scattering principle to measure particles of sizes less than 10µm. The unique data acquisition and calibration techniques used in the product ensure high accuracy and long term reliability. |
