Accurate air quality monitoring from vehicles
SENSOR BASED | BEST AVAILABLE ACCURACY
The Kunak AIR can be used in mobile applications due to its built-in GPS to geolocate every sample. It can be easily adapted to work in motion thanks to specific housing.
It consists of a plastic shell printed on silicone mould with magnet support with a specific internal design that ensures proper laminar flow as well as allows the correct measurement and assures high-quality data.
The shield protects the device from direct solar radiation as well as fast changes of atmospheric pressure, air currents, temperature and humidity transients to guarantee a correct performance.
This type of instrument is powered by a rechargeable battery with the car’s 12 Volt socket. Dimensions: 21 x 21 x 13 cm.
Parameters:
CO NO NO2 O3 SO2 H2S | PM1 PM2.5 PM10
Temperature, humidity, atmospheric pressure and dew point.
Benefits
This mobile monitoring shell enables collecting accurate real-time data of air pollutants. Data is stored onboard and is sent to the cloud via 2G/3G/4G. To access the data simply access the cloud platform. Data can be downloaded and viewed in .TXT and .CSV formats.
Sensors are housed within allowing users to measure as many gases as they wish (maximum 4 gases and particulate matter at once). Also, the shell includes a GPS that tags the location of each measurement and allows the visualization of the data on a map during all the tracking.
We enable decision making with large and accurate environmental data

(1) Measurement range: Concentration range measured by the sensor.
(2) Resolution: Smallest unit of measurement that can be indicated by the sensor.
(3) Temperature range: Interval of temperatures that the sensor could be exposed to.
(4) RH range: Interval of humidities that the sensor could be exposed to.
