Device group: Portable gas detectors
Device type: AirTECH duo+

AirTECH duo+ portable detectors are used to measure carbon dioxide (CO2) concentration in the range 0 ÷ 10% vol. and oxygen in the range 0 ÷ 25% vol. typically to control the atmosphere in fruit and vegetable storage facilities.

The AirTECH duo+ detectors use an optical carbon dioxide (NonDispersive Infra Red - NDIR) and an electrochemical oxygen sensor with an extended service life. The concentrations of carbon dioxide and oxygen are shown on two LED displays.

The detectors are equipped with a gas sampling system which includes: pump, internal dust filter, external gas pipe with universal tip, and external filter protecting against water suction.

All detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 standard (PCA accreditation no AP150).
