Introduction: FDO-99SH fluorescent dissolved oxygen sensor is a product specially designed for water environment monitoring and sewage treatment, which can quickly and accurately measure the concentration of dissolved oxygen in water. The working principle of fluorescence quenching is equipped with precise phase detection technology and a brand-new packaging process, which greatly improves the reliability, stability and service life of the product. The low power consumption and various signal output methods adopted by the product can facilitate customers to meet various different field conditions. Features: 1. Stable measurement, no drift; 2. Comes with temperature compensation; 3. No need to calibrate, 3D calibration has been done at the factory 4. No need to replace solid electrode or membrane/electrolyte; 5. No flow rate or agitation requirements; 6. Will not be "poisoned" by sulfides; 7. Not affected by "thermal disturbance"; 8. Not subject to cross interference from the following substances: H2S, pH, CO2, NH3, SO42-, Cl-, Cl2, etc.; 9. The service life of the fluorescent film can reach more than 1 year; 10. Ultra-low power consumption, can be powered by solar batteries Technical Parameters: Measuring range: Dissolved oxygen 0 － 20mg/l Saturation 0-120% Resolution: 0.01mg/l Measurement accuracy: Dissolved oxygen: ±1% F.S temperature: ±0.5℃ Response time: less than 60 seconds (T90) Working temperature: -10 － 55℃ Working pressure: 0.5MPa Protection level: IP68 Anti-interference: not interfered by the following substances: H2S, pH, CO2, NH3, SO42-, Cl-, Cl2, etc. Measuring foil life: 3 years Sensor shell material: 316L Installation method: 3/4 "NPT thread installation Electrode size: φ41*140mm
