Dissolved Oxygen Sensor
FDO-99 Optical Dissolved Oxygen Sensor
FDO-99 Optical Dissolved Oxygen Sensor employs advanced fluorescence quenching technology to measure the dissolved oxygen content in water. The sensor requires minimal maintenance and offers an extended service life. It is also less affected by common interfering substances, resulting in superior accuracy and stability.
Product Features
- No replacement of solid-state electrodes, membranes, or electrolytes is needed; requires minimal maintenance.
- Consumes no oxygen during measurement; has minimal flow or stirring requirements.
- Utilizes imported German fluorescent membranes, ensuring high measurement linearity and minimal long-term drift.
- The sensor membrane boasts an average service life of over 2.5 years.
- Stable measurements unaffected by common interfering substances such as H₂S, CO₂, NH₃, SO₄²⁻, Cl⁻, Cl₂, etc.
- Features fully digital signal output and supports a wide power supply voltage range.
- Integrated temperature sensor for automatic temperature compensation.
- Built-in protection against reverse connection of power supply and misconnection between power and RS-485 lines.
