Fluorescence DO Probe Meter Trace Dissolved Oxygen Sensor

Short Description:

The Luminsens Trace Dissolved Oxygen Sensor is a cutting-edge solution designed for precise measurement of trace-level dissolved oxygen (DO) in various water environments. Leveraging self-developed fluorescent material, this sensor operates on the principle of fluorescence quenching, eliminating oxygen consumption during measurement and ensuring maintenance-free operation. Its innovative design offers a long service life, rapid response to environmental changes, and robust anti-interference capabilities, delivering stable and reliable data even in challenging conditions. The sensor can be seamlessly integrated with both portable fluorescent dissolved oxygen analyzers and online monitoring systems, adapting to diverse detection needs—from on-site field surveys requiring mobility to continuous industrial process monitoring. With a measurement range of 0–2000 ppb for dissolved oxygen and 0–50°C for temperature, it caters to applications where micro-level DO accuracy is critical, such as semiconductor manufacturing, pharmaceutical water treatment, and ecological research.
