The FECS40-1000 is an electrochemical-type sensor designed for detecting carbon monoxide. Its unique leak-proof structure makes it suitable for various monitoring and detection applications.

The sensor exhibits linear output characteristics at 20˚C and shows temperature dependency in its sensitivity, as depicted in the provided graphs.

• Detection Gas: Carbon Monoxide
• Detection Range: 0 ~ 1000 ppm
• Maximum Overload: 1500 ppm
• Output Signal: 70 ± 15 nA/ppm
• Repeatability: ±2%
• Resolution: 1 ppm
• Typical Baseline Range (Pure air): -2 ppm to +3 ppm
• Typical Response Time (t90): < 30 sec
• Baseline Shift (-20 ~ 50˚C): < 10 ppm
• Long Term Output Drift: < 5% /year
• Expected Life Time: 3 years
• Operating Temperature: -20 ~ 50˚C
• Operating Humidity: 15 ~ 90% RH
• Operating Pressure Range: 1013 hPa ±10%
• Recommended Load Resistor: 10 Ω
• Bias Voltage: Not required
• Position Sensitivity: None
• Recommended Storage Temp.: 0 ~ 20˚C
• Cap Color: Red
• Weight: 4.5g (approx.)

The sensor's response to interference gases is minimal, with significant cross-sensitivity only to hydrogen at 100 ppm resulting in less than 40 ppm CO equivalent.
