uRADMonitor model CITY is an automated, monitoring station that tracks a total of 6 important air quality parameters including PM2.5, PM10, CO, O3, SO2 and NO2. It is compliant to international requirements on determining the Air Quality Index. It comes in a rugged aluminum enclosure with wall mounting support. The data is exported to the uRADMonitor network with Wifi or LORAWAN, and can be accessed in real time using the cloud API interface or directly via the local network.
It comes with:
Power adapter, antenna, instructions
Available, limited stock.
uRADMonitor model CITY uses a high quality laser scattering sensor to measure the Particulate Matter PM2.5 and PM10 concentration in air. There are four additional electrochemical sensors to measure Carbon Monoxide, Sulphur Dioxide, Nitrogen Dioxide and Ozone. A built in fan assures an active air flow stream across the sensing elements.

Particulate matter PM2.5
Particulate matter PM10
|0 μg/m³||1000 μg/m³|
|* Winsen ZE03-O3||Ozone||0 ppm||20 ppm|
|* Winsen ZE03-CO||Carbon Monoxide||0 ppm||1000 ppm|
|* Winsen ZE03-SO2||Sulphur Dioxide||0 ppm||20 ppm|
|* Winsen ZE03-NO2||Nitrogen Dioxide||0 ppm||20 ppm|
* The 4 electrochemical sensors can be replaced with any combination of sensors for the following gases and ranges:
|CO||Carbon monoxide||0 - 1000ppm|
|O2||Oxigen||0 - 25%VOL|
|NH3||Ammonia gas||0 - 100ppm|
|H2S||Hydrogen sulfide||0 - 100ppm|
|NO2||Nitrogen dioxide||0 - 20ppm|
|HF||Hydrogen fluoride||0 - 10ppm|
|SO2||Sulfur dioxide||0 - 20ppm|
|CL2||Chlorine gas||0 - 10ppm|
|O3||Ozone||0 - 20ppm|
|C2H4||Ethylene||0 - 100ppm|
|CH2O||Formaldehyde||0 - 10ppm|
|ETO||Ethylene oxide||0 - 20ppm|
|H2||Hydrogen gas||0 - 1000ppm|
|HCL||Hydrogen chloride||0 - 20ppm|
* All sensors are individually tested and calibrated.
Air pollution is the single largest environmental cause of premature death in urban Europe and transport is the main source. The 2008 Air Quality Directive, now under review, obliges member states to cut exposure to fine particulate matter by an average of 20% by 2020, based on 2010 levels.
The National Emissions Ceiling Directive caps some emissions including particulate matter (PM) and nitrogen dioxide (NOx) at national level. A revised version of the directive is as of 2016 under scrutiny by the Council of Ministers and European Parliament. Across the EU in 2013, nitrogen dioxide (NO2), which is mostly produced by traffic, caused 68,000 premature deaths. The Dieselgate scandal exposed how Volkswagen had gamed NO2 emissions tests.
Ozone (O3) killed 16,000 and small particulate matter (PM2.5) caused 436,000 deaths in the same year. PM2.5 particles, microscopic specks of dust and soot caused by burning fossil fuels, can enter the lungs and bloodstream.
Air pollution has different particulate matter (PM) components – smoke, dirt and dust form coarse particles known as PM10 and metals and toxic exhaust from smelting, vehicle exhaust, power plants and refuse burning forming fine particles called PM2.5.
uRADMonitor CITY is equipped with all sensors required to compute the Air Quality Index as defined by several international standards on air quality and give a direct assessment on the pollution problem and possible infringements.
The model CITY is designed as a fixed monitoring station. It comes in 2 variants, with the same sensors but offering different connectivity options: Wifi and LoraWAN. It takes any voltage in the 6V - 28V interval and uses less than 1 Watt of power to run. It can be powered using a small solar panel making it the perfect remote surveillance monitor. This unit doesn't have a screen, it works as a monitor and the data can be viewed remotely on a computer or on a mobile device.
|Voltage||External||6V - 28V|
|Connectivity||4 options||WiFi and LoRaWAN|
Your uRADMonitor CITY can be mounted both indoors and outdoors, but not directly exposed to sun, to avoid overheating in warmer areas. A covered spot with some shadow if installed in the free air, is ideal. The unit has a rugged aluminium enclosure that is not rainproof due to the air vents. Make sure that nothing is blocking the air vents. The enclosure has wall-mounting brackets, making installation easy. Connect the uRADMonitor to the power source using a DC adapter with voltage between 6V and 28V.
