Device group: Ventilation controllers
Device type: Senseair
Device model: aSENSE-D

SenseAir is a modern, microprocessor-controlled detector of carbon dioxide (CO 2 ), temperature (T) and humidity (RH). They monitor the fundamental parameters of indoor air quality in buildings. Their primary use is control of ventilation and air conditioning in public/commercial/industrial buildings in accordance with client needs. They enable significant savings in ventilation operating costs without sacrificing air quality.

Areas of ​​application

  • public buildings,
  • mushroom farms,
  • greenhouses (amount of crop yield),
  • fruit and vegetable storage (long-term storage),
  • breweries, gas storage facilities and other facilities where CO 2 is a technological medium or by-product (OHS).


  • highly selective measurement based on NDIR absorption,
  • no disturbance from other gases,
  • total resistance to periodic exceeding of the measuring range (up to 100% by volume),
  • long service intervals due to internal auto-calibration procedure;
  • all detectors are calibrated in GAZEX’s own Calibration Laboratory operating in accordance with PN-EN ISO / IEC 17025 (PCA accreditation No. AP150).
