1. What does a dissolved oxygen analyser online do?

Ans - An instrument that analyses the amount of dissolved oxygen in a liquid or gas sample is known as an online dissolved oxygen analyser. In aquatic systems like rivers, lakes, and seas, it is used to monitor the quality of the water and the aquatic life there.

2. How does a dissolved oxygen analyzer operate online?

Ans - An online dissolved oxygen analyzer measures the sample's oxygen content by how much light it absorbs using a sensor. Typically, a photoelectric cell serves as the sensor, converting light absorption into an electrical signal. Then, after being processed and amplified, this signal is shown on a screen or computer interface.

3. What advantages can online dissolved oxygen analysers offer?

Ans - In order to monitor and manage water quality, an online dissolved oxygen analyzer can deliver precise and timely observations of dissolved oxygen levels. It may be used to monitor and assess changes in aquatic ecosystems as well as identify potential pollution sources.

4. What kinds of samples can be measured by an online dissolved oxygen analyzer?

Ans - In most liquid and gas samples, including water, wastewater, and air, dissolved oxygen levels can be measured using an online dissolved oxygen analyzer.

5. How frequently should a dissolved oxygen analyzer be calibrated online?

Ans - In order to assure accuracy, an online dissolved oxygen analyzer should be calibrated at least once a year. The sensor should also be checked frequently, and it should be changed if necessary.
