At present, the biotoxicity analyzer has a large number of application cases in the fields of water conservancy, hydrological and water quality toxicity research, reservoir water quality monitoring and early warning, and multiple projects. It has been well used and meets industry testing standards. It can provide toxicity warnings for more than 3000 pollutants in the sample, and then judge the toxicity strength in biology with high sensitivity. The biotoxicity detection method is a toxicity detection technology based on biosensors, which can effectively detect sudden or destructive water source pollution. The Holder Electronic Portable Biological Toxicity Tester is a device that is easy to operate and highly sensitive. It uses bioluminescence detection technology and advanced photomultiplier tubes (PMT) to detect changes in the luminescence of luminescent bacteria during the analysis process. It can quickly detect toxicity in accidents or emergency situations caused by human contamination of drinking water and wastewater. We use highly pure and stable freeze-drying reagents for Vibrio fischeri, which comply with ISO11348-3 and the Technical Regulations for Monitoring the Biological Toxicity of Wastewater - Acute Toxicity Testing of Luminescent Bacteria - Fischer Vibrio Method standard method. Vibrio fischeri is non-toxic and cannot survive in freshwater systems, and will not cause secondary pollution.

Biological toxicity testing technology originated in the 1960s and is the "gold standard" in the biological toxicity testing industry. This technology applies the principle of biosensing (luminescent bacteria method) to quickly determine broad-spectrum pollutants in water. The Holder electronic biotoxicity analyzer is widely used for emergency monitoring of water sources, effluent from water purification structures, and factory water, playing an important role in environmental monitoring, water supply, disease control, and public health management.
