1. What is an online DO/oxygen analyser, exactly?

Ans - An instrument used to measure the amount of dissolved oxygen in a water sample is known as an online DO/oxygen analyser. In industrial and environmental applications, it is primarily used to check water quality.

2. How does a DO/oxygen analyzer operate online?

Ans - In order to measure the amount of dissolved oxygen in the water, an online DO/oxygen analyzer examines a sample of the water through a probe. The probe measures the sample's oxygen content using a combination of electrodes and sensors.

3. What advantages do online DO/oxygen analysers offer?

Ans - Accurate, real-time measurements of dissolved oxygen concentrations in a water sample are provided by an online DO/oxygen analyzer. This can be used to keep an eye on the quality of the water and find any impurities that might be dangerous to both people and aquatic life.

4. What are an online DO/oxygen analyser's limitations?

Ans - An online DO / oxygen analyzer is not appropriate for detecting oxygen concentrations in extremely hot or acidic or alkaline environments. To maintain accuracy, it must also be calibrated frequently.

5. What safety measures need to be followed while utilising an online DO/oxygen analyser?

Ans - Wearing safety gloves and eyewear is crucial when using an online DO / oxygen analyser. The instrument needs to be linked to a reliable power supply and positioned in a well-ventilated environment. Care should be taken when handling the sample to prevent contamination.
