Great Lake（GLI）He is a new member of Hash Corporation in the United States1970Since the beginning of the year30 For many years, we have been committed to providing online water quality analysis and detection instruments for water supply, sewage, and industrial process control. and1992Year by yearISO9001authentication.
GLIproduction5500 Series dissolved oxygen sensors andGLIofD63TheD53TheD33andPRO-D3Used in conjunction with dissolved oxygen analyzer or transmitter.
Its feature is the use of an integrated replaceable membrane head component, which simplifies the tedious and time-consuming operation of replacing a new membrane. Due to each component including a pre installed film, electrolyte, and electrode, the replacement of the component will be able to replenish the consumables required by the sensor. The sensor uses the Clark measurement technique with three electrodes. The third electrode has better long-term polarization, which makes the sensor more accurate and stable. The self-cleaning option includes a compressed air cleaning system that can be programmed to automatically clean the sensor film.

5500 pole method dissolved oxygen electrodeApplication field
1Mainly used for dissolved oxygen detection in urban and industrial wastewater treatment plants, typical applications include:

· Aeration tank

· aerobic/Anaerobic digestion tank

· Factory water

2It is also applicable for the determination of dissolved oxygen in various water bodies such as natural water, sewage, and saltwater.
working principle
5500 The working principle of the series dissolved oxygen sensor is to insert two metal electrodes into a small chamber filled with electrolyte, which is sealed with a selective thin film. Water and soluble ions cannot pass through this membrane, but oxygen and a certain amount of other gases and hydrophilic substances can pass through this thin film. By immersing the sensor in water, dissolved oxygen measurement can be performed. Due to the effect of the primary battery or external voltage, a potential difference is generated between the electrodes. This potential difference causes metal ions to enter the solution at the anode, while oxygen passing through the membrane is reduced at the cathode. The current generated by this is directly proportional to the transfer rate of dissolved oxygen through the membrane and electrolyte, and therefore the current is proportional to the partial pressure of oxygen in the water sample at a given temperature.
GLIof5500 The series dissolved oxygen sensor uses polarographic Clark cell technology and consists of a three electrode system: a gold cathode, a silver anode, and a silver reference electrode. Using a constant voltage to polarize the silver reference electrode for voltage stabilization results in a more stable potential compared to traditional dual electrode systems, as it does not generate sufficient interferenceD.O.Measured current. The voltage stabilization design of the reference electrode ensures long-term polarization stability throughout its service life, enablingGLISensors have higher accuracy and stability.
