As we know, water pollution refers to the water body because of the intervention of a certain substance, resulting in changes in many characteristics, affecting the quality of water. Cause damage to the environment and harm to human health!

Among them, E. coli groups are an important indicator in drinking water. It indicates the degree of fecal contamination of the water body, and the higher the number of E. coli groups, the more serious the pollution degree of the water body. In the drinking water quality sanitation standards, the E. coli index should not be more than 3 per liter of water.

So If You Want to Know the Situation of the E. coli in the Water Please Look Down!

If you want to know the situation of E. coli in the water, you need to use a water quality monitor! The instrument is specially used to monitor various indicators in sewage, and the instruments used for different indicators are also different. One of the instruments used for E. coli is, of course, an E. coli analyzer. There are many methods to monitor E. coli, such as: multi-tube fermentation, filtration membrane method, enzyme substrate, etc.

The WECT-900 Escherichia coli online analyzer produced by Hangzhou Modyi-Tech uses the enzyme substrate method, which is also the international standard method. The principle that the light signal changes in direct proportion to the reaction between the enzyme and the bacteria culture reflects the total amount of bacteria or coliform bacteria in the sample. In addition, Escherichia coli test technology is a kind of Escherichia coli detection system based on biosensing technology, which provides an effective detection means to deal with water supply pollution. The number of E. coli in water samples can be expressed by comparing the degree of light intensity weakening of the solution with the non-toxic control blank test. The instrument has the characteristics of automatic quality control and calibration to ensure the consistency and reliability of test results.
