Product Description
The AQMS-09 Ambient Air Quality Monitor Station is an integrated open pollution source online monitoring terminal, designed for continuous outdoor ambient air quality measurement.
This unit adopts pump-suction gas & particle sampling method, equipped with dynamic heating (DHS) humidity compensation and cross-interference compensation technology for gas sensors, greatly improving data accuracy in high humidity complex environments.
It can simultaneously detect particulate matters (PM2.5, PM10), gaseous pollutants including SO₂, NO₂, O₃, CO, H₂S, NH₃, as well as noise and meteorological parameters: temperature, humidity, atmospheric pressure, wind speed & wind direction.
Built-in 4G/GPRS wireless transmission module, the monitor uploads real-time monitoring data to the cloud platform, supporting multi-platform synchronous data upload. Breakpoint resume function guarantees over 99% data transmission rate even under unstable network conditions.
Modular and low-power design supports flexible expansion of monitoring factors. Optional 7-inch internal display and external LED outdoor screen, alarm lights for on-site data visualization and over-limit warning.
Wide working range: -30~+55℃, 0~95%RH, suitable for unattended long-term operation in remote sites, construction sites, industrial parks and reservoir areas.
Features:
It is a low power machine, modular design, can freely combine and expand monitoring factors.
No need to change the sampling cutter, it can detect the PM2.5, PM10, TSP at the same time; Resolution can reach 0.1 μ g/m3
Adopting high-precision light scattering, electrochemical, and photoionization detection technologies to effectively ensure data quality;
Equipped with dynamic heating (DHS) humidity compensation function and cross interference compensation function for gaseous pollutants to ensure data accuracy;
Equipped with breakpoint resume function, ensuring an effective data transmission rate of over 99%;
Adopting 4G full network wireless communication, supporting multi platform data synchronization upload;
Support the linkage function with pollution control facilities.
Can add external facilities such as LED outdoor display screens, alarm lights, etc.
