Domestic high-end zirconia oxygen analyzer achieves import substitution, Tianfen Instruments promotes technological upgrading in the energy industry

Recently, the zirconia oxygen analyzer independently developed by Anhui Tianfen Instrument Co., Ltd. has been successfully applied in a coal-fired boiler project of a power plant under the National Energy Group, replacing the same type of equipment from the original imported brand ABB. With its excellent pressure resistance, high precision, and stability, the equipment performs excellently under harsh working conditions, receiving high recognition from users, marking a significant technological breakthrough in China's high-end industrial analytical instruments in the coal-fired power generation field.

Innovative technology breaks the import monopoly
The zirconia oxygen analyzer used this time adopts the wear-resistant ceramic sheath technology specially designed by Tianfen Instruments, solving the industry pain point that traditional zirconia oxygen probes are easily worn and have a short lifespan in high-temperature, high-pressure, and high-dust environments. Compared with imported equipment, its wear resistance is improved by 30%, the measurement accuracy reaches the industry-leading level of ±0.5%, and the operational stability is significantly enhanced, greatly reducing the equipment maintenance frequency and downtime risk. The technical director of the power plant said: "After the equipment was put into operation, the boiler combustion efficiency optimization effect is obvious, the data feedback is real-time and accurate, and it fully meets the stringent requirements of ultra-low emission transformation."

Full-scenario coverage replaces imported zirconia oxygen analyzers
After years of technological research and development, Anhui Tianfen Instruments has now formed a complete product matrix of high-end zirconia oxygen analyzers, which can perfectly replace ABB, Rosemount, Ametek, GE, Siemens, Zillox, Novatek, Yokogawa Japan, Fuji Japan, Norfatek, Shifumei, and Watson Canada and more than ten international brands of zirconia oxygen analyzers. Its core technological advantages include:

Intelligent operation and maintenance system ：Integrates automatic calibration and automatic purging functions to reduce manual intervention;

Extreme working condition adaptability ：Special alloy probe and multi-layer protective structure, realizing triple protection against corrosion, vibration, and scouring;

Multi-scenario solutions ：For complex process scenarios such as garbage incineration, hazardous waste treatment, and acid production, the sensors are enhanced with sulfur-resistant coatings, platinum coatings, and imported CPUs to optimize program algorithms, improving service life and reducing measurement errors.

Environmental protection industry welcomes domestication opportunities
Driven by the "dual carbon" goals, Tianfen Instruments' innovative products have been implemented in many domestic benchmark environmental protection projects. Comparative tests at a garbage incineration power plant show that its equipment reduces data volatility by 60% in oxygen content monitoring in key links of dioxin control, helping customers pass EU emission standard certification. The general manager of the company said: "We are accelerating the layout of sensor research and development in emerging fields such as hydrogen energy and carbon capture, with the goal of achieving independent and controllable industrial analytical instrument full industrial chains within three years."

Currently, Anhui Tianfen Instruments has established strategic cooperation with the five major power generation groups, many large chemical enterprises, and metallurgical and steel enterprises, with the proportion of domestic substitution projects exceeding 70%. With the transformation and upgrading of China's high-end manufacturing industry, the performance advantages and cost competitiveness of domestic analytical instruments will be further released, injecting new impetus into the high-quality development of the energy and environmental protection industry.

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
