Biological toxicity monitoring instrument detection

2024-01-10 13:45

A biological toxicity monitor is a toxicity detection instrument based on biosensing technology. It uses the internationally recognized best model organism - zebrafish - as a biosensor to determine the toxicity of pollutants in water by measuring the behavior of fish.

This method has the advantages of being fast and inexpensive. And obtain experimental results that are close to humans, helping us achieve continuous monitoring of water quality and timely warning of water pollution events.

The characteristics of biological toxicity monitoring instruments:

It has a wide range of applications and can monitor various water bodies, such as rivers, reservoirs, water supply systems, water plant water intakes, and drainage systems.

The response is sensitive and rapid, with a sensitivity of less than 0.1TU to toxic and harmful pesticides, heavy metals, etc.

The acute toxicity test requires 48 hours to reflect the toxicity, and the water quality toxicity monitoring instrument can issue an alarm within a few minutes.

Taking heavy metal cadmium as an example, a response time of 0.7mg/l can emit a yellow alarm signal within 5 minutes.

Strong anti-interference ability, separating the observation device from the breeding box, eliminating the influence of external environmental factors on the monitoring signal, and avoiding signal interference caused by probe observation, ensuring the observation environment and enhancing the reliability of the results.

Stable and reliable performance, the instrument adopts a high-performance digital camera system, which can capture up to 25 biological images per second and achieve a tracking rate of over 98% for organisms;

Equipped with pre filtration system and water temperature stabilization system; Simultaneously monitoring multiple fish achieved the goal of obtaining stable and reliable biological motion parameters.

Continuous real-time monitoring, which can run continuously for 24 hours. No matter when water quality abnormalities occur, administrators can detect water quality problems through various alarm methods, greatly improving the efficiency of water quality monitoring. Reduced the losses caused by water pollution incidents.

A comprehensive statistical algorithm, the biological toxicity monitoring instrument has a powerful database and expert statistical analysis system. Through statistical algorithms, the impact of toxicity and non toxicity on fish behavior can be distinguished, ensuring the accuracy of monitoring and early warning.

Communication function: When there is an abnormality in water quality, the monitoring system will immediately issue alarm information to the manager through various methods such as mobile SMS, LAN, and remote client, in order to respond to water pollution incidents.

Easy to operate and maintain, using cheap and easily obtainable zebrafish as indicator organisms. Regular replacement of the organisms is sufficient to ensure the long-term stable operation of the instrument. The cleaning of filters and breeding boxes is also very convenient, and the overall operating cost is low.

Complementing physical and chemical instruments, RTB reserves the interface for connecting to conventional water quality physical and chemical monitoring data, which can further analyze sudden changes in physical and chemical data. On the one hand, it supplements biological warning, and on the other hand, it is conducive to tracing the cause of alarms and reducing the occurrence of false alarms.

The biological toxicity monitoring instrument can be equipped with auxiliary devices, and a sand filtration device has been added, making it more widely used for online detection of industrial wastewater, etc. Expanded the scope of use of biological toxicity monitoring devices.
