KFDO600 Low Cost Good Quality Dissolved Oxygen Meter Water Quality For Aquaculture 304 Stainless Steel Probe

Product Introduction

The fluorescence method dissolved oxygen measuring instrument is based on fluorescence quenching principle.The fluorescent material at the front of the sensor is a special platinum porphyrin compound with a polyester foil that allows gas molecules to pass through. The surface is coated with a black light-blocking material to avoid interference by sunlight and other fluorescent substances in the water.
When blue light hits the fluorescent material, the fluorescent material is excited and emits red light. Since oxygen molecules can carry away energy (quenching effect), the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules.By measuring the phase difference between the excitation red light and the reference light and comparing with the internal calibration value, the concentration of oxygen molecules can be calculated.After linearization and temperature compensation, the final value is output.



Performance characteristics:

1. Principle of fluorescence quenching, no electrolyte digestion, maintenance-free
2. No need to replace the fluorescent cap, the use cost is lower;
3. No oxygen consumption, no flow rate and agitation requirements
4. No interference from chemicals such as sulfides
5. High resolution and measurement accuracy
6. Chinese menu operation is simple, easy to operate and master
7. Special thickened cap film, not easy to wear, longer service life
8. The unique protective cover design prevents irreversible damage caused by the cap film hitting hard objects during the sensor reuse process

Electrode installation

Electrodes are very delicate components and must be installed correctly. The wrong installation can result in damage to the electrodes or irreversible damage.The electrode is installed in pipeline.Immersion. Both French and French installations are available.

Do not put the electrode directly into the water. Instead, select the electrode mounting bracket or the flow cup for fixation.Before installation, please make sure to use the raw material belt (3/4 thread) to do waterproof sealing work, to avoid water entering into the electrode and causing short circuit of the electrode cable.

During water outage, make sure that the electrode is immersed in the tested liquid or wear the protective cap with the protective liquid inside. If the temperature is low and the water is stopped for a long time in winter, add antifreeze device or take back the room to add water and store.Otherwise, the service life will be shortened.

Technical Parameters of Fluorescence Dissolved Oxygen Analyzer

Q&A

What is zero drift?
It refers to the size of the indicating value of the automatic analyzer changing within a certain period of time when the zero correction liquid specified in this technical requirement is used as the sample for continuous testing.

What is Range drift?
refers to the change of the indicating value of the automatic analyzer in a certain period of time when the range correction liquid specified in this technical requirement is used as the sample for continuous testing.

What is Mean fail-free?
continuous running time refers to the ratio of the total running time (h) of the automatic analyzer to the number of failures (times) during the test period, which is shown in "MTBF". The unit is h/time.

What is response time (T90)?
electrodes from range correction fluid to zero correction fluid, the determination of displayed value range correction liquid concentration 90%.
