Citicel (often written CiTiceL / City Technology) Oxygen Sensors are electrochemical gas sensors designed to detect and measure oxygen concentration (O₂) in air or gas mixtures. These sensors produce a measurable electrical signal proportional to the oxygen content, making them suitable for industrial monitoring, emissions analysis, safety systems, and oxygen analyzers. They are widely used in gas detectors, environmental monitoring instruments, automotive analyzers, PSA systems, and other oxygen‑sensitive applications.

• Electrochemical Measurement Principle: Generates a current or voltage signal in proportion to oxygen concentration.

• Wide Measurement Range: Many models cover 0–100 % O₂ or part‑range variants (e.g., 1–25 % vol.) depending on type.

• Fast Response Time: Typical response times are <5–15 seconds (T₉₀), enabling timely detection.

• Linear Output: Signal output (mV or mA) changes proportionally with oxygen level, easing integration with measurement electronics.

• Robust Operating Conditions: Designed to work in common industrial temperature and humidity ranges (e.g., –20 °C to +50 °C with non‑condensing humidity).

• Compact & Lightweight: Small size allows integration into handheld or fixed gas detection equipment.

✔ Industrial Gas Detection & Safety: Monitors oxygen levels in manufacturing, processing, tanks, and confined spaces.
✔ Emission & Environmental Analysis: Used in emission analyzers to check combustion efficiency and ambient O₂.
✔ Oxygen Analyzers & Controllers: Integrated into instruments for measuring and controlling oxygen in gas streams.
✔ PSA & Gas Separation Plants: Monitors O₂ concentrations in PSA nitrogen generation and similar systems.
