How to choose a biological toxicity tester

　　Nowadays, environmental pollution has become the biggest problem facing our country. In the process of operation of some industrial equipment, a lot of sewage is often discharged. If these sewage cannot be effectively treated in time, it will have a serious impact on people's drinking water problems and even threaten people's health.

　　The biological toxicity tester [Holder HED-DX] is a new generation of biological acute toxicity analyzer for laboratory use. It is a toxicity detection system based on bioluminescent sensing technology. It performs qualitative and quantitative detection based on the changes in the luminescent intensity of luminescent bacteria during metabolism. Compared with traditional fish, water fleas and other aquatic organisms as biological detection methods, the luminescent bacteria method is simple, rapid, sensitive, highly adaptable, reproducible, highly accurate, low-cost, and widely used. It is a water quality toxicity rapid detection instrument designed for environmental pollution, emergency accidents, security inspections and routine testing. It can be used for the overall toxicity detection of heavy metals, poisons, nerve agents, pesticide preparations and other substances in on-site water.

　　Instrument features:

　　1. Comply with national standards (GB/T154411995) and international standards (ISO11348-3);

　　2. A biological early warning system that is sensitive to more than 3,000 toxic compounds;

　　3. Get results within 15 minutes after sample preparation, fast, reliable and reproducible;

　　4. The test results are highly correlated with other traditional toxicity analysis methods and can be applied to emergency water pollution detection, helping users to monitor in real time whether the drainage complies with local regulations and emission standards;

　　5. Use silicon photomultiplier tube to greatly improve detection sensitivity;

　　6. It has an independently developed biological toxicity darkroom automatic lifting detection device to solve the problem of open cover testing being affected by strong light in the industry;

　　7. Portable PVC engineering box design, can be carried out for on-site testing;

　　8. 7-inch large display touch screen, eliminating the need for cumbersome button operations, more convenient;

　　9. Android intelligent operating system, smarter and more user-friendly;

　　10. With RJ45, WIFI, 4G and Bluetooth connection and transmission functions, it can realize wireless transmission to relevant monitoring and supervision platforms, realize real-time data, and better meet the scenario requirements of regulatory departments.
