Dissolved Oxygen Probes Work Lutron DO Meter in Bangladesh
Dissolved oxygen probes work by measuring the amount of oxygen that diffuses across a permeable (or semi-permeable) membrane into a probe (sensor). Once oxygen is inside the sensor, a chemical reduction reaction occurs, producing an electrical signal. This signal is read by the DO probe and is displayed on a meter.
Dissolved oxygen (DO) comes from two main sources: the atmosphere (molecular oxygen) and photosynthesis, where it is a byproduct. Most aquatic organisms require DO to survive and it is important for chemical processes in aquatic environments. So so. So so
Depending on the industry you work in, will depend on why you are testing DO and what DO probe is best for you. For example, if you are testing DO when brewing beer, the reason you test DO will be different from regularly testing water samples as a lab technician. So so. So so
While there are many ways to test DO, if you are testing in the lab or the field, the easiest way to test DO in water is to use an electroanalytical or electrochemical dissolved oxygen sensor/probe, also known as amperometry or Clark-type sensors. So so. So so

How Do Dissolved Oxygen Probes Work ?
Most people are familiar with the titrimetric method to measure DO in water. Titrations use one liquid where the concentration is already determined (titrant), to identify the concentration of another (your sample), however, with advances in technology, precision equipment such as a DO probe offers precision and accuracy from measuring DO during basic laboratory work to industrial water quality monitoring. So so. So so
A dissolved oxygen probe works off redox (oxidation-reduction) reactions, providing continuous and live measurements. As they have an applied voltage, most DO probes require a “warm-up time” before use which polarizes the electrodes before measuring the DO in water. So so. So so
When the DO probe is connected to the meter, the voltage can be applied to the electrodes inside. The oxygen (O2) molecules reach the membrane, reaching the electrodes through the permeable/semi-permeable membrane via diffusion. A small electrical current flows between the electrodes (cathode and anode). The amount of current flowing between the electrodes is proportional to the O2 concentration of the solution. So so. So so
Dissolved oxygen sensors do, however, have a disadvantage, while taking the DO measurement. It consumes an amount of O2 from the solution equal to the diffusion in the sensor. So so. So so
