CO-AX Electrochemical Carbon Monoxide Gas Sensor For Air Quality Monitoring

Product Specification

                  CO-AX Electrochemical Carbon Monoxide Gas Sensor For Air Quality Monitoring Environmental Monitoring Systems

1. Product Features:

• High Measurement Accuracy & Sensitivity: Delivers a sensitivity range of 55 - 100 nA/ppm in 400 ppm CO, with a resolution of < 0.5 rms noise (ppm equivalent). This ensures precise detection of even small changes in CO concentration, meeting strict monitoring requirements.
• Fast Response Speed: Boasts a T90 response time of < 30 seconds when transitioning from zero to 400 ppm CO. It can quickly capture sudden increases in CO levels, providing timely alerts to potential hazards.
• Low Drift for Long-Term Stability: Features minimal zero drift (< 0.2 ppm equivalent change/year in lab air) and sensitivity drift (< 6% change/year in lab air with monthly testing). This guarantees consistent performance over extended periods, reducing the need for frequent calibration and maintenance.
• Wide Operating Range & Environmental Adaptability:
  • Operates reliably within a temperature range of -30 °C to 50 °C, a pressure range of 80 - 120 kPa, and a humidity range of 15 - 90% rh (continuous). It can adapt to various harsh or variable environmental conditions, such as cold outdoor winters or humid industrial areas.
  • Has an over - gas limit of 4000 ppm, enabling it to withstand temporary high - concentration CO exposure without permanent damage, enhancing its durability in extreme scenarios.
• Long Service Life & Storage Life: Offers an operating life of > 24 months (until 80% of the original signal, with a 24 - month warranty) and a storage period of 6 months at 0 - 20 °C (when stored in a sealed pot). This provides long - term value for users and simplifies inventory management.
• Compact & Lightweight Design: Weighs < 6 g, making it easy to integrate into various devices. Its multiple standard package options (20mm diameter, 32mm diameter, 20mm diameter with extra height, and miniature) cater to different installation needs of portable and fixed - site instruments.
• Low Zero Current Interference: Has a zero current of < ±3 ppm equivalent in zero air, minimizing false alarms caused by background electrical noise. It ensures that the detection results accurately reflect the actual CO concentration in the environment.

2. Product Applications:

• Portable Gas Detection Instruments: Ideal for integration into handheld CO detectors used by professionals like firefighters, industrial workers, and emergency responders. These devices allow on - site, real - time monitoring of CO levels in confined spaces (such as basements, sewers) or accident scenes, ensuring the safety of personnel.
• Fixed - Site Detection Systems: Used in fixed gas monitoring stations installed in industrial facilities (e.g., chemical plants, power plants, steel mills), where CO may be produced during combustion or chemical processes. The sensor provides continuous monitoring to prevent equipment damage and protect workers' health.
• Indoor Air Quality Monitoring: Suitable for residential, commercial, and public buildings (such as homes, offices, schools, and hospitals) to detect CO leaks from gas appliances (e.g., stoves, water heaters) or heating systems. It helps maintain a safe indoor environment and alerts occupants to potential CO poisoning risks.
• Environmental Monitoring Networks: Integrated into regional or urban environmental monitoring networks. These networks collect CO concentration data across a wide area to analyze air quality trends, support environmental policy - making, and provide the public with real - time air quality information.
• Automotive & Transportation Sectors: Used in vehicle exhaust gas monitoring systems (for emission testing) or in - cabin air quality monitoring. It helps ensure that vehicle emissions comply with environmental standards and that the air inside the vehicle is safe for passengers.
