Systech ZR810 Zirconia Oxygen Analyzer — O2 in Nitrogen, 0-10/0-100ppm & 0-10% O2
Overview
The Systech ZR810 Zirconia Oxygen Analyzer, configured here for oxygen measurement in nitrogen gas streams and waste nitrogen lines, is a panel-mounted, continuous process oxygen analyzer built around Systech’s precision zirconium dioxide (ZrO2) electrochemical sensor. This configuration covers trace-to-percent oxygen detection with three switchable ranges — 0–10 ppm, 0–100 ppm, and 0–10% O2 in N2 — making it suited to nitrogen purity verification and waste-nitrogen monitoring in industrial gas, electronics, and inert-atmosphere processing facilities. Seven Star LLC supplies the Systech ZR810 to laboratories, gas plants, and process facilities across Oman and the GCC needing dependable, fast-responding oxygen measurement on nitrogen service.
Nitrogen used for blanketing, purging, or inerting is only as good as its oxygen content allows. Even small oxygen ingress into a nitrogen supply can compromise inert atmosphere processes such as soldering, heat treatment, or product blanketing, leading to oxidation defects, contamination, or safety risk. The ZR810’s zirconia sensor technology, shared across Systech’s ZR800 analyzer series, is engineered specifically to catch this kind of oxygen ingress quickly and reliably, with a local panel-mounted indicator giving operators an immediate, on-the-spot reading.
Operating Principle
The Systech ZR810 uses a high-purity, high-density stabilized zirconia ceramic sensing cell operating at high temperature, where the zirconia electrolyte becomes conductive to oxygen ions. A reference gas on one side of the cell and the sample nitrogen stream on the other create an oxygen partial-pressure differential across the cell; this differential drives oxygen ion migration through the zirconia lattice, generating a DC voltage proportional to the oxygen concentration ratio. A high-speed microprocessor linearizes this logarithmic cell output into a direct, stable digital reading on the analyzer’s local indicator, with a 4–20 mA output available for integration into a plant control or monitoring system. The ZR800 platform this ZR810 configuration is built on delivers a response time of 90% of a step change within approximately 5 seconds, among the fastest available in zirconia-based oxygen analysis.
Engineering Design
Built for continuous industrial duty, the Systech ZR810 is offered in panel-mount, bench-top, and wall-mount configurations, with this unit specified as panel-mounted for integration into a control cabinet or local instrument panel alongside a 110 VAC, 50 Hz power supply. The instrument’s microprocessor-controlled menu interface allows operators to configure alarm setpoints, calibration intervals, and output scaling to match a specific nitrogen monitoring application without specialist analytical training. The zirconia sensor itself is a low-maintenance, durable component designed for long service life under continuous exposure to nitrogen and waste-nitrogen gas streams, and the instrument carries an IP66 rating, making it dust-tight and weather-resistant for installation in demanding industrial gas-handling areas.
