ONLINE OXYGEN GAS PURITY ANALYZER An online oxygen gas purity analyzer is a device used to continuously monitor the concentration of oxygen (O₂) in gas streams, typically in industrial applications such as chemical processing, pharmaceuticals, oil and gas, power plants, and environmental monitoring. These analyzers provide real-time data on the purity of oxygen, ensuring the proper quality and safety of processes where oxygen levels are critical. Key Features: Real-Time Monitoring: Continuously measures oxygen concentration, providing immediate feedback on any deviations from desired purity levels. Accuracy: High-precision sensors provide accurate oxygen measurements, often in the range of parts per million (ppm) or percentage. Variety of Measurement Techniques: Electrochemical Sensors: These sensors are common due to their sensitivity to low oxygen levels. They typically consist of a cathode and an anode immersed in an electrolyte. Oxygen reduction at the cathode generates a current proportional to oxygen concentration. Paramagnetic Sensors: These sensors use the magnetic properties of oxygen to measure its concentration. Zirconia Sensors: Used mainly for high-temperature and high-pressure applications. They operate based on the measurement of oxygen ion conductivity at high temperatures. Alarms and Safety: Many analyzers come with integrated alarms and alert systems that notify operators of abnormal oxygen levels, ensuring safety in processes that require strict oxygen control. Data Logging: Some models are equipped with the ability to record data, providing historical records for analysis, traceability, or compliance with regulatory requirements. Calibration: Online analyzers often have automated calibration features to ensure accurate readings over time, minimizing manual intervention.
