Product Description

 

                 A3EF A3EFF A7EF Electrochemistry Carbon Monxide Gas sensor 0-2000ppm For Gas Analyzers Carbon Monoxide

 

Key Features:

  • High Specificity for NH₃: Optimized electrode materials and electrolyte design ensure minimal cross-interference from common gases (e.g., CO, H₂S, NO₂) in most environments.
  • Stable 3-Electrode Design: The third electrode (counter electrode) reduces polarization effects, lowering zero drift and improving measurement consistency over long-term use.
  • Low Power Consumption: Compatible with battery-powered portable detectors, thanks to its low operating current requirements.
  • Easy Integration: Standard electrical parameters (bias voltage, load resistor) and compact form factor simplify integration into fixed or portable gas detection systems.
  • Robust Environmental Adaptability: Operates reliably in a wide temperature and humidity range, suitable for both indoor and outdoor industrial scenarios.

Typical Applications:

  • Industrial Safety Monitoring: Chemical plants, fertilizer production facilities, and refrigeration systems (where NH₃ is used as a refrigerant) to detect leaks and protect workers.
  • Environmental Monitoring: Wastewater treatment plants, livestock farms, and agricultural facilities to monitor NH₃ emissions and comply with environmental regulations.
  • Portable Gas Detectors: Handheld safety devices for personnel working in NH₃-exposed environments (e.g., maintenance technicians, farmers).
  • Fixed Gas Alarm Systems: Permanent installations in warehouses, storage facilities, and production areas to trigger alarms when NH₃ concentrations exceed safe thresholds.
  • Medical & Laboratory Equipment: Specialized analytical instruments for NH₃ concentration measurement in research or clinical settings.
