Detects extremely low concentrations of toxic gases (typically at ppm-level detection limits).
Concentration and signal exhibit a linear relationship, facilitating quantitative analysis.
Designed with gas-specific electrode reactions, resisting cross-interference (e.g., CO-dedicated electrodes are minimally affected by hydrogen).
Minimal long-term drift for reliable operations.
It is designed primarily for car parks and underground parking garages to monitor and detect toxic carbon monoxide (CO) gas generated by incomplete vehicle engine combustion.
The 2-wire design combines both power and signal transmission into a single cable system. This removes the need for additional 24V power cables, significantly simplifying the installation process and reducing wiring costs across large parking environments.
The detector features a conformal coating on its internal electronics. This coating forms a highly durable barrier that protects components against water, dust, oil, and moisture, making it ideal for tough car park environments.
Yes. The AT2004BIV-CO is designed with excellent compatibility and expansion options, enabling easy integration with central control monitoring systems to automatically trigger ventilation systems or alarms.
The sensor has a measuring range of 0 to 1000 ppm and offers a typical operating lifespan of 5 years under normal operation conditions.
