DO Probe

DO Probe This type of sensor is Optical, using the principle of Fluorescence to measure oxygen content in water. The wavelength wavelength is the principle of light, and the concentration of light that hits the lens. Then calculate the difference between the return and the oxygen value in the water

◼ Polarographic Cell : Use metals such as gold, platinum, or palladium as the cathode
◼ Galvanic Cell : Use lead with gold. Or lead with money as a cathode

Polarographic Cell and Galvani Cell use the principle of electrochemistry. The electrochemical inside the probe includes: Polarity cathode electrode anode solution Electrolyte And the membrane is a material that is able to select only oxygen through it. Polarographic Cell uses external voltage to help increase the voltage to the cells from the battery. Voltage Source Galvanic Cell This probe is a self-polishing amperometric cell

◼ Optional Sensor : Fluorescence is used to measure oxygen content in water by applying wavelength wavelength and controlling the density of light reflected on the lens. During Send-Back Calculated as oxygen in water
