System Introduction
E. coli (bacterial community) online analyzer USES the international standard, the method of enzyme and bacterial culture reaction is directly proportional to the light signal changes after this one principle, reflects how much the total number of bacteria and coliform bacteria in the sample.
Working Principle
The E. coli (bacterial community) test technology is a bacterial detection system based on biological sensing technology that provides an effective means of responding to water pollution. The measurement principle uses the standard method specified in the international standard ISO 9308, which can ensure compatibility with various water quality for online automatic monitoring of E. coli (bacterial community). The number of E. coli (bacterial community) in the water sample can be represented by the degree of weakening of the solution light intensity compared with the toxin-free blank control experiment.

Scope of System Application
Widely used in drinking water source safety, emergency assessment and multi-bacteria determination, can be used for early warning of water pollution incidents, but also can be used to warn of general water pollution incidents and food poisoning incidents.
Advantage
Easy to oPerate
Integrated report generation, real-time monitoring of the whole reaction process, and dynamic display of the test project response curve.
Flexible Detection
The measurement period is short, the response speed is fast, and the detection process can be set freely.
Quality Control and Calibration
Automatic quality control and calibration to ensure the consistency and reliability of test results.
Fully Automatic Control
The user can program the detection parameters to adapt to different applications, automatically start the cyclic detection mode for suspicious samples, and start the control center alarm when the machine calls again after power failure, automatically resume the working state.
Reliable Operation
Low cost of use and maintenance, automatic completion of sample and reagent dispensing, mixing and cleaning, avoid cross-contamination, easy maintenance, low operating cost, small reagent consumption, weekly maintenance, only need to replace reagents, disposable consumables cost is low.
