Biological toxicity water quality monitoring instrument

The water quality biotoxicity detector measures the acute biotoxicity caused by heavy metals and other organic pollutants in the tested environmental sample by measuring the changes in the luminescence of luminescent bacteria. Compared with traditional methods of using fish, fleas, and other aquatic organisms as biological detection methods, the luminescent bacteria method is simple, fast, sensitive, adaptable, has good repeatability, high accuracy, low cost, and wide applicability. It can be used to determine the biological toxicity of toxic compounds, wastewater, and waste.

ＵＴＯＸ－ ２０００Biological toxicity water quality monitoring instrumentDeveloped based on the principle of comprehensive toxicity of luminescent bacteria, meeting the requirements of ISO11348-32007 and GB/T15441-1995 standards. It has the characteristics of continuous, fast, and automatic monitoring, and at the same timehighThe sensitivity can directly and objectively reflect the acute comprehensive toxicity of water to organisms, providing important data reference for monitoring and early warning of water quality and environment.

ＵＴＯＸ－ ２０００Biological toxicity water quality monitoring instrumentIt is an upgraded version of UTOX-1000, which not only has the characteristics of UTOX-1000 stability, sensitivity, and automatic monitoring, but also has the features of automatic bacterial recovery, long maintenance cycle, and waste liquid separation.

Features of online automatic water quality monitoring instrument:

1. Automatic recovery function of bacterial strains

The instrument is equipped with an automatic bacterial recovery system, which can achieve low-temperature storage of ≥ 9 freeze-dried bacterial strains, fully automatic injection of recovery solution, recovery of bacterial strains, and automatic replacement of bacterial solution

2. Dual standard testing system

Free selection of two bacterial strains, Vibrio fischeri and Vibrio cholerae

The test results can be displayed according to ISO standards or calculated using the standard curve drawn in GB/T15441-1995

Dual optical path comparison testing technology: synchronized to ensure the timeliness and effectiveness of test data

Accurate and efficient temperature control device: using computer CPU cooling control technology, combined with server level cooling fans, can quickly drop to the target temperature

Simultaneously ensuring long-term temperature stability through reasonable CPU control algorithms

Photon acquisition algorithm: Collect data multiple times within a specified time and filter to obtain the average value. At the same time, automatically compensate and correct the problem of low measurement values caused by the gain attenuation of the photomultiplier tube.

Scope of application

Drinking water sources, boundary water bodies, and groundwater; Water supply plant inlet; Entrance of biochemical treatment tank in sewage treatment plant; Industrial gathering areas, hospitals, and enterprise sewage discharge outlets.
