The air quality monitoring station for professionals
After 7 years of designing and deploying small air quality stations all over the world, we have created the new Kunak AIR Pro, a huge evolution of our previous sensor-based air quality monitoring station designed to solve all the lifecycle challenges of an air quality product, its operation and maintenance, as well as the need of every environmental project.
Its multipollutant cutting-edge design includes environmental sensors as well as connectors for external weather sensors or probes which, together with its solar panel operation and real-time wireless data transmission makes the Kunak AIR Pro the most advanced air quality monitoring station on the market.

(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.
(5) Operating life: Lifetime of the sensor in normal conditions. Long exposures to humidity above 85% can damp the sensor and affect the measurements.
(6) Guarantee range: Limit covered by the guarantee.
(11) LOD (Limit of detection): Measured quantity value giving the probability of falsely claiming the absence or presence of a component.
(14) Performance limit level: Readings below this level can have lower performance than specified. Measured against reference instrument.
(15) Typical accuracy: Is obtained as the mean absolute error (MAE) between KUNAK AIR hourly measurements and reference instruments in 1 to 8 months field test between -10 to +30ºC in different countries.
(16) Typical 90% confidence interval: 90% of the hourly measurements obtained in 1 to 8 months field tests between -10 to +30ºC in different countries are below this absolute error comparing to reference instruments.
(17) Typical precision R2: The average R² between Kunak AIR Pro hourly measurements and reference instruments in 1 to 8 months field tests between -10 to +30ºC in different countries.
