OMD-501X Oxygen Analyzer | Product Specifications
Oxygen Analyzer:
The OMD-501X Oxygen Analyzer combines a compact 1/4 DIN panel-mount design with Southland Sensing’s precision electrochemical oxygen sensor technology. Designed for integration into process equipment and control panels, the OMD-501X provides reliable and cost-effective trace, percent, and oxygen purity measurement with an intuitive, easy-to-use interface.
Trace oxygen measurement ranges include 0–10 PPM, 0–100 PPM, 0–1,000 PPM, 0–10,000 PPM, and 0–25% O₂. Percent and purity measurement ranges include 0–1%, 0–5%, 0–10%, 0–25%, and 0–100% O₂.
The analyzer can be configured by the user for trace PPM, percent, or oxygen purity measurement by selecting the appropriate oxygen sensor through the built-in menu. This allows the same analyzer platform to support a wide range of oxygen measurement applications.
The analog output can be manually assigned to a selected measurement range through the analyzer menu. Alternatively, the auto-range function can be used in conjunction with the Range ID output to communicate the active measurement range to a PLC, DCS, or other process control system.
The remote oxygen sensor housing is connected to the analyzer by a 72″ (1.8 m) cable, allowing the sensor to be positioned near the sample point while the analyzer remains mounted in the control panel. Process gas connections are available with compression tube fittings or a KF-40 sensor housing for direct installation into compatible process equipment.
Requisitos de Alimentação
Input Power: 100–240 VAC, 50/60 Hz or 10–28 VDC

Oxygen Sensor Technology:
The oxygen sensors used in the OMD-501X are based on proven galvanic electrochemical fuel cell technology. All oxygen sensors are manufactured in-house by Southland Sensing Ltd. under a controlled quality program to provide consistent performance, accuracy, and long-term stability.
Multiple sensor chemistries are available to accommodate different process gas compositions. Standard sensors are designed for applications containing background gases such as hydrogen, helium, and hydrocarbons. Acid-resistant sensors are available for applications containing carbon dioxide and other acid gas backgrounds, including many natural gas streams.
Southland Sensing oxygen sensors are completely self-contained and require minimal routine maintenance, with no electrodes to clean or electrolyte to replenish.
Southland Sensing’s precision electrochemical oxygen sensor technology provides reliable oxygen measurement while maintaining long sensor life across a wide range of industrial applications.
Oxygen Sensors:

Oxygen sensors should be periodically calibrated to maintain measurement accuracy. Southland Sensing recommends calibration approximately every 2–3 months, or at an interval appropriate for the specific application and operating conditions.
The sensors provide excellent linearity and can be conveniently calibrated using ambient air when appropriate. For applications requiring greater calibration accuracy or traceability, a certified span gas can be used.
