Trace oxygen analyzer, oxygen analyzer, zirconia oxygen analyzer, ppm oxygen content analyzer

Zirconia-based trace oxygen analyzers (typically with a measurement range of 0.01 ppm to 5,000 ppm O₂) offer key advantages: high-temperature stability, ppm‑level accuracy, rapid response, and continuous operation. They are widely used for trace oxygen monitoring, inert‑atmosphere protection, and quality control of high-purity gases. **Metallurgy / Steel Industry (Heat Treatment / Protective Atmospheres):** Applications include nitriding furnaces, annealing furnaces, heating furnaces, converter flue gases, and glove boxes. Functions: In controlled-atmosphere furnaces (ppm‑level), precise oxygen control (10–1000 ppm) prevents oxidation and decarburization of workpieces, enhancing hardness and wear resistance. In vacuum/glove box environments, maintaining O₂ levels below 50 ppm protects lithium‑battery materials, rare metals, and precision components. **Semiconductors / Electronics (High‑Purity Gases / Cleanroom Environments):** Applications encompass diffusion/oxidation furnaces, wafer annealing, LED epitaxy, vacuum chambers, glove boxes, and high‑purity nitrogen, argon, and hydrogen pipelines. Functions: Ultra‑high‑purity gases (0.01–1 ppm) ensure process yield by preventing oxidation defects in silicon wafers, chips, and LED dies. Inert atmospheres (10–100 ppm) maintain an oxygen‑free environment, safeguarding sensitive materials and devices. **Air Separation / Industrial Gases (High‑Purity Gas Quality Control):** Applications include air‑separation units (N₂/O₂/Ar), high‑purity gas filling, pipeline transport, and cylinder inspection. Functions: Monitoring trace oxygen levels (0.1–10 ppm) in N₂/Ar streams ensures compliance with purity standards (e.g., high‑purity nitrogen ≥99.999%). **Food / Pharmaceutical Industries (Preservation / Aseptic Conditions):** Applications cover food packaging (nitrogen flushing or modified‑atmosphere packaging), pharmaceutical lyophilization and packaging, fermentation tanks, and aseptic isolators. Functions: Residual oxygen levels in packaging (0.1%–5%) inhibit oxidation and mold growth, extending shelf life for meat products, fruits, vegetables, and pharmaceuticals. **Laboratories / Research (Precision Environments):** Applications include materials R&D, battery laboratories, catalytic reaction studies, inert‑gas‑protected experiments, and glove boxes. Functions: Precise control of oxygen partial pressures (from ppm to % levels) enables simulation of oxygen‑free or low‑oxygen conditions, ensuring experimental reproducibility and data reliability. **Technical Specifications:** - Measurement range: 0.1 ppm–20,000 ppm; 0–20.6%; 0–100% - Output signal: 4–20 mA; load resistance ≤500 Ω - Communication interface: RS‑485 - Resolution: 0.01 ppm - Repeatability: ±0.5% of full scale - Basic error: ≤±1% (full scale) - Stability: ≤±1% (after 4 hours of continuous calibration) - Response time: Within 5 seconds when a standard gas is introduced to the sensor, reaching 90% of the final reading - Sample gas flow rate: Adjusted via flow meter, typically maintained at 0.1–0.2 NL/min - Ambient temperature: 0°C–45°C - Power supply and power consumption: 220 VAC ±10%, maximum power consumption 150 W - Sample gas temperature: 0–50°C - Sampling method: Either suction‑type or direct‑injection - Operating pressure (without pump): 0.05 MPa < inlet gauge pressure < 0.35 MPa, with stable atmosphere - Operating pressure (with pump): Micro‑positive, micro‑negative, or atmospheric pressure - Background gases: He, Ar, CO₂, N₂, and other inert gases mixed as needed - Gas‑line interface: 1/8-inch φ6 ferrule or quick‑connect fitting
