Description

The LuminOx Flow-Through Optical Oxygen Sensor from SST is designed to enable efficient sample gas management by allowing a clean gas stream to flow directly into the sensor, completely isolating it from the surrounding process environment.

Part of SST’s LuminOx sensor range, this variant (LOX-02-F) offers an enhanced response time compared to standard models, making it ideal for applications where fast and accurate oxygen measurement is critical.

Based on SST’s proprietary luminescence quenching technology, the sensor measures ambient oxygen without consuming it—providing a longer service life than traditional galvanic alternatives. Its solid-state construction is free from lead or liquid electrolytes, ensuring compliance with environmental regulations and suitability for a wide range of industrial and scientific uses.

The sensor includes built-in temperature and barometric pressure compensation and communicates directly via USART, eliminating the need for external signal conditioning. It delivers real-time readings of oxygen concentration, partial pressure, temperature, and atmospheric pressure—making it a complete solution for integration into your system.

With its robust flow-through housing and minimal cross-sensitivity to other gases, the LuminOx oxygen sensors are well-suited for precise, reliable oxygen monitoring in complex gas environments.
