Product Overview:
Fecal Escherichia coli comes from the intestines of humans and other warm blooded animals and is excreted through feces. The survival time of fecal Escherichia coli in the natural environment is closest to that of pathogenic bacteria, and fecal Escherichia coli has the highest number in the intestine. Therefore, the content of fecal Escherichia coli can better reflect the content of intestinal pathogenic bacteria in water bodies, which meets the requirements for fecal pollution detection of indicator bacteria in water quality. Moreover, the survival time of fecal Escherichia coli in water and its resistance to disinfectants and adverse factors in water are similar to pathogenic bacteria. In practical work, fecal Escherichia coli is often used as an indicator organism to evaluate the hygiene quality of water.
The fecal Escherichia coli online monitoring system is a water quality multi parameter microbial online automatic monitoring product developed with enzyme substrate microbial detection technology as the core. This is the first time that laboratory enzyme substrate microbial detection technology has been applied to on-site automatic monitoring of water quality, filling a gap both domestically and internationally. This product can detect various components such as total bacterial count, total fecal Escherichia coli, heat-resistant fecal Escherichia coli, and Escherichia coli in surface water, groundwater, seawater, and drinking water, and can be combined arbitrarily. Breaking through the concept of a single on-site water quality monitoring instrument, building a multi-functional and arbitrarily combined on-site water quality automatic monitoring laboratory platform. The enzyme substrate microbial detection technology has the advantage of rapid online automatic detection, achieving online cultivation and detection of multiple microorganisms within 6-18 hours.
This product is suitable for: hospital sewage, drinking water sources, surface water quality automatic monitoring stations, sewage treatment plant outlets, etc.
Product features:
Easy to operate, meets unmanned online continuous monitoring, and can remotely upload detection data results.
Multiple independent constant temperature cultivation detection systems ensure relatively high-frequency sampling, with a minimum sampling frequency of 4 hours.
Built in turbidity correction function can reduce the impact of increased turbidity during microbial cultivation on detection results.
The concentration range of the test water sample is wide to avoid the occurrence of fully positive results.
Automatic pipeline disinfection and cleaning to eliminate cross interference of water samples.
