High Stability
Maintains consistent performance over a long period, suitable for various industrial scenarios and portable gas detectors.
Replaceability
Can serve as a substitute for the NE4-CO sensor, ideal for cost-sensitive applications (e.g., underground parking monitoring systems).

Working Conditions:

Series Comparison:

The NE4-CO-SI belongs to the NE4-CO series, which also includes the standard NE4-CO sensor.
Compared to consumer-grade sensors, the NE4-CO series offers:
Higher signal output and lower detection limits.
Excellent gas selectivity, durability, and response speed.
The NE4-CO-SI balances performance with cost-effectiveness, making it suitable for applications where budget constraints are a priority.
