OMD-190 Oxygen Analyzer Southland Sensing
Overview
The Southland Sensing OMD-190 is an online oxygen analyzer in a panel mount package with a remote sensor housing, providing trace, percent, or purity analysis from 0.01 ppm to 100% oxygen. It combines precision electrochemical sensor technology with an intuitive user-friendly interface.
The analyzer offers auto-ranging or manual range mode, two adjustable alarm contacts with delay mode, and a direct fit replacement design for existing panel installations.
Engineering & Design
The OMD-190 is built around a precision electrochemical sensor that measures oxygen across the full trace-to-purity span, with an accuracy of plus or minus 1% of full scale. The response time is T90 in 7 seconds, supporting fast detection of oxygen changes in the sample.
The anodized aluminium enclosure with a backlit LCD display is designed for general purpose panel mounting, and the power supply accepts 10-28 VDC or 100-240 VAC for flexible installation. The isolated 4-20 mA analogue output and bi-directional Modbus RS485 ASCII communication interface the analyzer with control systems.

Oxygen analysis from trace to purity levels needs a capable analyzer, and the OMD-190 oxygen analyzer delivers, which is why Seven Star LLC supplies the OMD-190 oxygen analyzer for process and safety applications.
For oxygen monitoring projects, the OMD-190 oxygen analyzer is the panel mounted choice, and Seven Star LLC supplies the OMD-190 oxygen analyzer with configuration guidance. The OMD-190 oxygen analyzer covers the trace to purity range, and the OMD-190 oxygen analyzer is supported by our team.
Why Seven Star LLC
Seven Star LLC supplies the OMD-190 oxygen analyzer for gas analysis projects across the Gulf, with verified specifications and technical support. Our team assists with range selection, sensor configuration, and panel installation planning.
We support process, safety, and laboratory customers with reliable B2B supply of oxygen analysis instrumentation throughout the GCC.
Installation & Operation
The panel mount package fits standard panel cutouts, and the remote sensor housing allows the sensor to be located at the sample point while the electronics stay in the panel. The 10-28 VDC or 100-240 VAC power options cover both plant and laboratory supplies.
Operation is straightforward with the backlit display and auto-ranging mode, and the two alarm contacts with delay mode support both process and safety alarm strategies. Modbus RS485 ASCII communication integrates the analyzer with DCS and SCADA systems.
Supply Chain & Sourcing
Seven Star LLC supplies the OMD-190 analyzer and its replacement sensors through the established SSO2 supply channel, protecting your analyzer investment with a dependable source of consumables.
Our team supports range identification for new installations and sensor life planning for existing panels across the Gulf.
For blanketing and purity applications, the analyzer is configured with the appropriate range and alarm set points, and the remote sensor housing can be mounted directly at the sample point to minimise response lag.
The auto-ranging mode simplifies operation when the oxygen level changes across ranges, and the analogue and Modbus outputs feed the DCS or SCADA. Periodic sensor checks and calibration keep the electrochemical measurement accurate over the sensor life.
