The OXUS OA‑Z‑03 is a compact oxygen analyzer designed for high‑range O₂ measurement (5–95%). It features a 12 VDC supply, ±2% accuracy, and dual output (mV / TTL RS‑485), making it suitable for industrial, marine, and combustion‑gas monitoring applications.
Oxygen Analyzer – OXUS OA‑Z‑03
The OXUS OA‑Z‑03 is a high‑range oxygen analyzer engineered for applications requiring accurate measurement of oxygen concentrations between 5% and 95%. Manufactured by OXUS Co. (Korea), the OA‑Z‑03 is widely used in industrial combustion systems, inert‑gas systems, process monitoring, and OEM installations.
Unlike the OA‑Z‑IG (0–25% O₂), the OA‑Z‑03 is optimized for environments where oxygen levels are significantly higher, making it ideal for process‑gas analysis, oxygen‑enrichment systems, and industrial safety monitoring. It operates on 12 VDC, offers ±2% accuracy, and provides both 1,000–5,000 mV analog output and TTL RS‑485 digital communication.
The OA‑Z‑03 uses a stable zirconia‑based sensing method, offering long lifespan, minimal drift, and fast response time. It is designed for panel‑mount integration and can be installed as a standalone analyzer or as part of a larger oxygen‑monitoring system.
