PDO portable fluorescence dissolved oxygen meter Introduction: The PDO portable fluorescence dissolved oxygen meter does not require polarization time for the dissolved oxygen probe when measuring dissolved oxygen. The PDO portable fluorescence dissolved oxygen meter does not require calibration, and the probe has been calibrated before leaving the factory. It can be directly measured without calibration during use. The dissolved oxygen meter is suitable for measuring the concentration or saturation of oxygen dissolved in water. Can be applied to aeration tanks, aerobic and anaerobic tanks, nitrification and denitrification tanks, etc. It can also be used in rivers, lakes, seawater, fishing grounds, etc. Features: 1. Innovative fluorescence method principle, no need to replace the membrane and electrolyte, basically maintenance free; 2. No need to replace the fluorescent cap, lower usage cost; 3. No oxygen consumption, no requirements for flow rate and agitation; 4. It is not affected by chemical substances in wastewater and can be applied in relatively harsh wastewater environments; 5. Almost maintenance free, which saves time and reduces the owner's costs; 6. Factory pre calibration, no calibration required during user use; 7. No polarization time, turn on the measuring instrument to start measuring; 8. Quick response with minimal stirring required; 9. Accurate measurement, with an accuracy rate of 99%; 10. Durable and sturdy, the sensor can maintain its accuracy even in the event of scratches and partial contamination, making it easy to clean; 11. Long lifespan, normal use can reach a lifespan of up to 5 years; 12. It performs well in small scales and is more suitable for sewage treatment engineering applications; 13. Large capacity storage space, can read data through USB interface without the need for driver programs.
