4O2-LQ Gas oxygen sensor


Basic Information:

  • Measurement Range: Typically 0–30% vol. O₂ (also available in specifications like 0–25% vol. O₂).
  • Model Examples: CITY brand 4-O₂ (Lq), product codes such as 2112B0231400 (CLE-0231-400).
  • Application Fields: Instruments and meters for oxygen concentration detection.

Technical Features:

  • Technology Principle: Adopts solid-state electrochemical technology with a three-electrode advanced design and standard liquid electrolyte, ensuring high stability.
  • Dimensions: Standard 4-series size.

Performance Parameters:

  • Output Type: Analog output.
  • Accuracy: Specific accuracy indicators may vary by manufacturer and batch, but generally meet the precision requirements for oxygen concentration detection in relevant scenarios.
  • Response Time: Quickly responds to changes in oxygen concentration (specific time parameters refer to the product manual).
  • Stability: Features good long-term stability due to its advanced design, maintaining accurate measurement performance over time.

Other Information:

  • Compatibility: Some 4O2-LQ sensors are compatible with related devices from other brands, such as certain models from RAE.
  • Working Environment:
  • Temperature: Typically operates within a wide range, e.g., -35°C to +70°C
  • Humidity: Usually 5%–100% RH (specific requirements depend on product specifications).
