KFDO900 220VAC Water Quality Sensor For Aquaculture Industrial

KFDO900 Dissolved Oxygen Meter Water Quality For Aquaculture Industrial

Product Introduction

Fluorescence method oxygen dissolved meter is based on the quenching principle of specific substances to active fluorescence in physics.The figure as follow is the schematic diagram of the sensor's work. The fluorescent substance at the front of the sensor is a special platinum porphyrin composite with polyester foil allowing gas molecules to pass through, and the surface is coated with a layer of black light-proof material to avoid interference from sunlight and other fluorescent substances in the water.

The modulated blue light shines on the fluorescent material and causes it to excite and emit red light. Since oxygen molecules can carry away energy (quenching effect), the time and intensity of red light excitation are inversely proportional to the concentration of oxygen molecules.We used the red light source synchronized with blue light as the reference, measured the phase difference between the excited red light and the reference light, and compared it with the internal calibration value, so as to calculate the concentration of oxygen molecules, and output the final value through temperature compensation.

Performance characteristics:

● Innovative fluorescence principle, no need to replace the diaphragm and electrolyte, basic maintenance free;
● No need to replace the fluorescent cap, lower use cost;
● No oxygen consumption, no flow rate and agitation requirements;
● will not be "toxic" because of sulfide, to overcome environmental interference;
● Free from cross interference of H2S, PH, CO2, NH3, SO4, CL-, CL2, etc.
● Higher resolution and measurement accuracy;
● The service life of the sensor is up to 5 years;

Apply:
Surface water, industrial sewage and municipal sewage

Q&A

Why is the effect of oxygen filling obviously better in winter than in summer?

The main reason is that the water temperature is lower in winter and the dissolved oxygen saturation is higher. On the contrary, the dissolved oxygen saturation is lower in summer.
