Trace Oxygen Analyzers

A Trace Oxygen Analyzer is a high-sensitivity instrument designed to measure very low levels of oxygen (O) in gas streams. It is widely used in industries where even minute amounts of oxygen can affect product quality or process efficiencysuch as in semiconductor manufacturing, inert gas blanketing, pharmaceuticals, petrochemicals, and metallurgy.

Trace oxygen analyzers typically use one of the following sensor technologies:

Electrochemical Sensor Accurate and compact; commonly used in portable units
Zirconia Sensor High-temperature applications and high accuracy
Paramagnetic Sensor Long-term stability, ideal for low O concentrations
Tunable Diode Laser (TDL) For high-precision, non-contact measurements
Key Features:
Ultra-low Detection Levels Down to ppm (parts per million) or ppb (parts per billion)

Fast Response Time Ideal for dynamic process control
Compact & Portable Options Available in portable or panel-mounted models
Digital Display Real-time oxygen reading with user-friendly interface
Analog & Digital Outputs 4-20 mA, RS-485, Modbus for PLC/SCADA integration
Alarm & Control Relays For safety and process automation
Sample Conditioning Systems Optional for high-moisture or pressurized gases
