Patented 3-electrode electrochemical cell design with ultra-low-noise potentiostat circuit achieves single-digit ppb detection limits for NO₂ and O₃.
Onboard DSP runs real-time cross-gas interference algorithms. Humidity and temperature cross-sensitivity are corrected at the sensor level before data output.
Continuous self-diagnostic monitoring of sensor health. Electrochemical cell impedance tracking predicts end-of-life 30 days in advance. No unexpected downtime.
Urban and industrial air quality stations. Multi-gas detection in a single compact module. EPA-equivalent measurement methodology.
Confined space gas monitoring for petrochemical, mining, and manufacturing. ATEX/IECEx-certifiable sensor elements available.
CO₂ and VOC-based demand-controlled ventilation. Optimize fresh air intake while minimizing energy consumption in commercial buildings.
