Czujnik CO2 AirTECH-mini


AirTECH-vento is a modern, digital, portable meter designed for control of carbon dioxide level in closed spaces. Except form the measurement functions it has an internal memory which registers the measurement results during 8 hour work day, calculating module also displaying present NDS level and an alarm arrangement, signaling optically and by sound exceeding of the set CO2 concentrating thresholds. Because of it, it is not only adequate for the industrial safety services but also for individual employer protection especially at risk of CO2 action of high concentration and for stating dynamic changes in the level of CO2 in the rooms of various type. 


  • brewery, distillery, and other plants of fermentation industry,
  • bottling plants of soft drinks,
  • CO2 cylinders warehouses,
  • fire extinguishing warehouses and the quarters with a fire extinguishing installation based on CO2.


  • highly selective measurement based on a principle of infrared flux NDIR absorption,
  • no influence from other gases, steams and moistures,
  • complete resistance to periodical exceed in the scope of measurement (up to 100% vol.),
  • constant presentation of CO2 level and constantly updated NDS value on a display,
  • optical alarm,
  • sound alarm,
  • long work time up to 12 hours (accumulator type Li-ion, without an effect of memory loading),
  • long service free period because of an internal auto-calibration procedure,
  • energonomic and esthetic casing,
  • standard equipment: a case, a belt clip, a battery charger,
  • OPTIONALLY: AirTECH-vento, scope: 0-2000 ppm, for efficiency control of the ventilation systems.
