Wall Mounted Online Optical DO Meter with 0.00-20.00mg/L Measuring Range ±2%F.S. Accuracy and 0.01mg/L Resolution

The online fluorescence dissolved oxygen detector is an intelligent instrument that measures dissolved oxygen using fluorescence method. Blue light excites a fluorescent layer, causing it to emit red light. The oxygen concentration is determined by measuring the phase difference between excitation red light and reference red light, corresponding to internal calibration values. This advanced technology ensures long-term stability, reliability and accuracy.

Featuring English menu operation, this instrument is widely used in chemical fertilizer production, metallurgy, environmental water treatment, pharmaceuticals, biochemistry, food processing, aquaculture, and tap water monitoring for continuous dissolved oxygen measurement.

Install the instrument in a clean, dry, well-ventilated location without vibration. Avoid areas with corrosive gases.

The wall-mounted installation requires fixing screws to the wall according to the instrument's mounting hole positions for secure attachment.

Do not immerse the electrode directly in water. Install the electrode into a bracket or flow cup. Before installation, use PTFE tape (3/4 thread) for waterproof sealing to prevent water ingress and potential short circuits in the DO electrode cable.
