Introduction Luminescence process of luminescent bacteria is a kind of physiological processes of metabolism of bacteria in the body, the glowing process are highly susceptible to the effects of external conditions.When the toxic and harmful substances contact with luminescent bacteria, water samples of toxic substances can affect the metabolism of luminescent bacteria, the luminous intensity weakening is directly proportional to the concentration of the toxic substance to the sample.With the traditional fish, algae, plankton compared to the biological detection method such as luminescent bacteria method is simple, rapid, sensitive, determination of drinking water, surface water, biological toxicity of sea water.Currently, the law has become the luminous bacteria as a kind of simple, rapid biological toxicity testing means, is widely used in quality control, environmental monitoring, aquaculture and other fields, and was listed in the international standard ISO11348. Portable analyzer biological toxicity of biological toxicity tests using luminescent bacteria method, instrument provides ATP, rapid measurement and the basic measuring three modes, satisfy the customer different testing requirements.System USES a portable design and true color touch screen, combining the guidance type menu operation, several minutes to get the test results, field very easy to use. Features 1 full Chinese color touch screen, simple operation, easy to field test on site 2, 5 minutes to complete testing, a comprehensive toxicity level detection can be qualitative identification of the sample 3 strains of reliable quality, stable performance and can detect heavy metals, organic and inorganic toxic substances, etc 4 equipped with computer expert software, convenient for data processing 5 equipped with 18 ℃ low temperature portable incubator, holding time can be up to 48 hours.Storage luminescent bacteria when used for field operations Technical parameter 1 Detection principle: photobacteria method 2 Testing time: 5 min 3 Early warning function: automatic excessive tip samples 4 Communication interface, USB interface 5 User interface: true color touch screen 6 Electrical source: 220 v, the built-in battery 7 The environmental temperature 5 ℃ to 40 ℃
