Portable Trace Micro ppb Dissolved Oxygen Analyzer Clark electrode
>>Principle
Based on Clark electrode technology, specifically designed for measuring trace-level (ppb level) oxygen concentrations in water.
>>Application
○ Detection and analysis of low-concentration dissolved oxygen in power plants, waste heat boilers, deoxygenated water, etc.
○ Trace oxygen detection in semiconductor ultrapure water.
>>Feature
High-Precision Sensor: Detection limit of 0.01 μg/L, resolution of 0.01 μg/L
Rapid Response: Typically requires only 3 minutes to measure from atmospheric O₂ to μg/L-level concentrations
Simplified Calibration: Ready for measurement upon startup; no prolonged electrode polarization needed
Extended Electrode Lifespan: Reduced replacement frequency and costs
Low-Maintenance Design: Electrode servicing interval of 4–8 months under normal use
Ultra-Low Power Consumption: Operates >1,500 hours on four AA alkaline batteries
Robust & Ergonomic: IP67 waterproof rating; magnetic attachment; lightweight (300g)
