Zirconium Oxide Oxygen Analyzer
The Single Channel Zirconia O2 Analyzer System delivers accurate O2 and humidity measurements utilizing Yokogawa’s zirconia oxygen analyzers for combustion monitoring and control, helping industries achieve lowered CO2, SOx, and NOx emissions. The oxygen analyzer system provides minimized downtime and simplified maintenance with advanced diagnostics, an intuitive design and technician training.
Zirconia Oxygen Probe System
The Zirconia Oxygen Analyzer System includes the ZR402G converter and ZR22 detector and is capable of measuring oxygen concentration or humidity in non-combustion applications with a single analyzer. Its LCD touch screen provides easy operation, and digital communications are standard, allowing for remote configuration and troubleshooting.
ZR402G Converter
The ZR402G converter is equipped with an LCD touch screen featuring an intuitive operating system with a variety of display modes and error codes with built-in error details. Other standard functions include measurement, calculation, and self-test maintenance functions to enable easier operation and troubleshooting.
ZR22G/ZR22S Detector
The ZR22G separate-type detector is an in-situ probe that uses a high-reliability zirconia sensor. The zirconia cell and heater assembly can be replaced in the field, reducing maintenance costs. The ZR22S separate-type detector for explosion-proof applications is also available and offers the following explosion-proof certifications:
- ATEX
- FM
- CSA
Features
Accurate Maintenance Scheduling with Advanced Diagnostics
Predictive diagnostics from the analyzer simplify troubleshooting and provide technicians with the necessary data to create a minimal calibration schedule.
Reduced Downtime with a Robust Cell Design
The probe's cell is designed with a large measurement surface area, making it less susceptible to contaminants, which allows for longer periods between cell replacements and calibrations.
Increased Measurement Availability with an Intuitive Design
The probe uses a long-life, high-reliability zirconia sensor and has an intuitive design that enables easy troubleshooting and repair in the field, minimizing downtime and reducing costs since technicians only need to replace the needed parts.
Increased Process Uptime with Customized Training Resources
Yokogawa’s knowledgeable representatives and support technicians provide operation and repair training for all Yokogawa products both in the factory and in the field. Training ranges from basic operation to advanced troubleshooting, helping you achieve more efficient operations and simplified maintenance.
