NE4-CO-SI Electrochemical Carbon Monoxide (CO) Gas Sensors
Basic Information:
Detected Gas
Carbon monoxide (CO)
Application Fields
Industrial alarm systems, underground parking lot monitoring, etc.
Measurement Range
0–1000 ppm
Performance Features:
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:
Temperature Range
-20°C–50°C
Humidity Range
15–90% RH (non-condensing)
Pressure
0.9–1.1 atm
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.
