Product Features
The enzyme substrate fluorescence detection technology can be used for multiple purposes with one machine. The test indicators are “coliform bacteria” and “feces”
“Coliform bacteria” and “Escherichia coli” can be freely switched.
Detection time: 4 to 16 hours, which is 2 hours shorter than the national standard.
The test values are accurate, and the relative error of the concentration index is ≤10%.
According to the actual characteristics of water samples, quantitative quality control bacteria are regularly used (in accordance with national standard methods) for on-site quality control to ensure the reliability of the results.
The fluorescence method is adopted, and there are no special requirements for the turbidity of water samples.
It adopts non-disposable reagents, which are low-cost and support a 15-day maintenance-free cycle.
It has an automatic water sample replacement function, reducing the impact of the previous water sample concentration. The residual concentration of the previous concentration is less than 0.001%.
The liquid seals in the system pipelines before and after the detection, in combination with the sealed detection system, completely isolate the outside world and eliminate the influence of the environment on the detection results.
