Comprehensive toxicity online monitor for water body

The online monitoring instrument for comprehensive toxicity of water is an online monitoring instrument for detecting the comprehensive toxicity intensity of water by using the changes of photosynthetic activity of planktonic algae under the stress of toxic pollutants. The instrument uses chlorophyll fluorescence as the probe of algae photosynthesis process to detect the photosynthetic activity of algae rapidly and nondestructively. The inhibition rate of photosynthetic activity of algae under toxic stress was obtained by the "control-test" dual channel test. Based on the dose-effect relational database between the toxicity intensity of pollutants and the photosynthetic inhibition rate of algae, combined with the threshold model of environmental stress, the rapid monitoring of comprehensive toxicity intensity of water and the real-time warning of ecological environmental risks were realized.

Comprehensive toxicity online monitor for water body

Product introduction

The online monitoring instrument for comprehensive toxicity of water is an online monitoring instrument for detecting the comprehensive toxicity intensity of water by using the changes of photosynthetic activity of planktonic algae under the stress of toxic pollutants. The instrument uses chlorophyll fluorescence as the probe of algae photosynthesis process to detect the photosynthetic activity of algae rapidly and nondestructively. The inhibition rate of photosynthetic activity of algae under toxic stress was obtained by the "control-test" dual channel test. Based on the dose-effect relational database between the toxicity intensity of pollutants and the photosynthetic inhibition rate of algae, combined with the threshold model of environmental stress, the rapid monitoring of comprehensive toxicity intensity of water and the real-time warning of ecological environmental risks were realized.

 

Product use

It highlighted emergency tracking and monitoring of water pollution accidents, rapid assessment of combined and unknown pollution levels, and continuous online monitoring and early warning of ecological and environmental risks to drinking water sources and good water bodies.

 

Product features

 

As the primary producer of water, planktic algae is sensitive to the toxicity of pollutants and sensitive to the risk of water ecological environment.

The "control-test" dual-channel cross-test mode greatly improves the reliability and stability of the biological police system;

The algae photobiochemical reactor can provide the tested algae species continuously for the long-term online test of water toxicity.

Self-cleaning sample injection and preparation device to ensure unattended continuous operation.
