Product Description:
YJJ CO-500 4R+ C03-0906-000 Electrochemical Carbon Monoxide CO Sensor for Multi-Gas Detector
Features:
CO - 500 4R + C03-0906-000 RAE Systems' three-electrode electrochemical carbon monoxide (CO) sensor, compatible with multi-gas detectors, is used for monitoring CO concentrations ranging from 0 to 500 ppm. It features linear output, rapid response, and long-term stability, and is suitable for industrial safety, emergency rescue, and indoor protection scenarios.
Key Parameters
Parameter Category Specific Parameter Remarks
Measurement Range 0-500 ppm (CO) Maximum overload 2000 ppm, over-range requires timely disengagement
Sensitivity 0.070±0.015 μA/ppm (20℃) Output linearly corresponds to concentration, facilitating signal conversion
Response Time T90 ≤ 30s Quickly captures concentration changes, meeting alarm timeliness requirements
Baseline (20℃) < ±0.2 μA Zero point stable, reducing false alarm rate
Baseline Drift (-20~50℃) 0-3 ppm CO equivalent Resistant to temperature and humidity changes, with strong environmental adaptability
Resolution 1 ppm Accommodates precise monitoring of low concentrations
Linearity Linear Stable full-range output, simple calibration
Long-term Drift < 2% Signal Value / Month Stable performance throughout the lifespan, reducing calibration frequency
Operating Conditions Temperature - 20~50℃; Humidity 15-90% RH (no condensation); Pressure 91-111 kPa Compatible with most indoor and outdoor industrial and civilian scenarios
Bias Voltage 0 mV No need for additional bias circuit, simplifying integration
Physical Characteristics Weight approximately 5g; Size φ20.2 × 16.6mm; No orientation sensitivity Compatible with portable and fixed equipment installations
Life and Warranty 2-year lifespan in air; Warranty period 12 months after delivery Reliable performance under original sealed storage conditions Working principle
Based on the three-electrode electrochemical principle: After CO gas diffuses into the sensor, an oxidation reaction occurs at the working electrode, generating an electric current. The magnitude of the current is proportional to the concentration of CO; the auxiliary electrode inhibits interference reactions, and the reference electrode stabilizes the working potential. Through circuit conversion, a readable concentration signal is obtained, enabling precise detection.
