Senzor de gaze

uRADMonitor modelul CITY este o stație automată de monitorizare care urmărește în total 6 parametri importanți de calitate a aerului, inclusiv PM2,5, PM10, CO, O3, SO2 și NO2. Stația respectă cerințele internaționale privind determinarea indicelui calității aerului. Aceasta se livrează într-o carcasă din aluminiu robustă cu suport pentru montaj pe perete. Datele sunt exportate în rețeaua uRADMonitor cu Wifi sau LORAWAN și pot fi accesate în timp real utilizând interfața API cloud sau direct prin rețeaua locală.

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.

* 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:

Symbol Gas Detection interval
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

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.
