Portable biological toxicity detector

Portable biological toxicity detectorIt is a product independently developed by Shenzhen Youwei Environmental Technology Co., Ltd. It is a fully automatic toxicity detector with a high-precision PID temperature control system. According to GB/T 15441-1995 "Determination of Acute Toxicity of Water Quality - Luminescent Bacteria Method" and ISO-11348-3 "Determination of Acute Toxicity of Luminescent Bacteria - Fischer Arc Freeze Dried Powder Method", the principle of acute toxicity of luminescent bacteria is used to detect the acute toxicity of water quality. When luminescent bacteria encounter toxic substances from the outside, their metabolism will be affected, thereby inhibiting the luminescence intensity. The degree of inhibition is related to the toxicity of the external toxic substances. This detector can quickly detect water pollution on site and is an effective supplement to conventional physical and chemical scientific instruments, providing a basis for the detection and evaluation of environmental quality.

Application areas:

*Environmental testing departments at all levels and disease prevention and control centers serve as emergency monitoring projects

*Testing of inlet and outlet water, processing water, surface water, and filtration toxicity in water quality treatment

*Detecting the acute toxicity of contaminated water bodies, as well as the acute toxicity of contaminated soil and coastal sediment

*Study the interactions between toxic elements and compounds - synergistic or antagonistic effects

Product Features:

*The instrument has 6 built-in sample grades and can sequentially measure 5 water samples with a minimum interval of 10 seconds

*Interference correction of colored sample solution: capable of performing interference correction of colored sample solution according to the requirements of the national standard GB/T 15441-1995

*The testing accuracy is equivalent to that of online toxic products and can be used for data assessment of online toxic products

*Equipped with portable kits such as a portable case, it can be used in the field or for emergency situations. The portable case can be used as an operating workstation

*Configurable data management software for computer online analysis, with measurement results that can be converted to EXCEL format
