1、 Principle and Product Introduction

The system is developed based on the principle of acute toxicity of luminescent bacteria, which can directly and objectively reflect the acute comprehensive toxicity of raw water to organisms (luminescent bacteria). It has the characteristics of continuous, rapid, and automatic monitoring, as well as good sensitivity and reliability; For pollution caused by accidents, intentional destruction, and other reasons, toxicity testing can be conducted30Quickly display drinking water and various surface waters within minutes/Toxicity in groundwater.

This online instrument system meets the requirementsISO 11384-3as well asGB/T 15441-2011The standard requirements ensure that relevant institutions can respond quickly to changes in water quality, providing a fast and effective method for comprehensive protection of water supply safety and environmental supervision, and thus providing important technical support for environmental pollution incidents, monitoring and early warning of the entire surface water body and drinking water, and effective control.
