FAQs

1. How is the value calculated and how are the samples incubated?

Analyzer’s is calculated by measuring the dissolved oxygen (DO) in the sample at the start and after 5 days. The difference in DO represents the oxygen consumed by biological activity. Samples are incubated at a constant temperature (typically 20?°C) in a dark environment to prevent photosynthesis, which could alter oxygen levels.

2. Why is the Analyzer important in quality testing?

Analyzer is an advanced solution designed for accurate and efficient measurement of Biochemical Oxygen Demand in water samples. With its precise measurement it is user-friendly and it can handle 1 to 8 samples at a time making it suitable for both small and medium scale testing. It uses differential pressure method and provides accurate measurement results comparable to those obtained using chemical dilution methods.

3. What is the importance of Analyzer in water quality testing?

analyzer measures the Biochemical Oxygen Demand of a water sample, which indicates the amount of oxygen required by microorganisms to break down organic matter in the water over a specific period, usually five days. is a key indicator of organic pollution in water. High values suggest a large amount of biodegradable material, which can deplete oxygen levels and harm aquatic life.

4. What types of water samples can be tested?

Analyzer can measure samples ranging from 0 to 1000 mg/L. The Analyzer can test a variety of water samples, including municipal waste water, industrial effluents, surface water, groundwater, industrial sewage, environmental monitoring and other fields water measurements.

5. What is the role of mercury in the Analyzer to calculate the value?

The sample to be tested is cultured in the Analyzer at a constant temperature of 20 ± 1 ? for five days, the water sample in the bottle will undergo the biological oxidation reaction at a certain stirring speed. The organic matter is transformed into oxides of nitrogen, carbon and sulfur, and the carbon dioxide gas is absorbed by sodium hydroxide. The oxygen in the upper space of the culture bottle continuously supplies the oxygen demand of the microorganism in the water sample, and the pressure difference is generated in the culture bottle. By detecting the height of mercury in the glass tube, the value of the water sample in the specified measurement period can be calculated.
