Embodiment Construction

[0014] A photoelectric comprehensive toxicity detector, wherein the sample 1 and the photoelectric sensor 2 are arranged in the first box space 18, and the rest of the circuit main body is located in the second box space 19, the sample 1 emits fluorescence, which is detected by the photoelectric sensor 2, The detection signal is processed by the pre-processing circuit 5. The pre-processing circuit 5 includes a two-stage amplifier circuit and an A / D conversion circuit. The converted signal enters the single-chip control module 7 for processing, and the single-chip control module 7 passes through the communication module. 9. Contact with the upper computer, display the processing results through the liquid crystal display module 11, store data through the data storage module 12, and perform command input through the keyboard interface 8. The air fan 3 and the air intake fan 4, the heat dissipation channel 13, the first air intake hole 14, the second air intake hole 15, the third ...

Abstract

The invention provides a photoelectric type comprehensive toxicity detector. A sample (1) and a photoelectric sensor (2) are arranged in a first box body space (18), and the other circuit main bodies are located in a second box body space (19). A radiation system comprises an air exhaust fan (3), an air inlet fan (4), a radiation channel (13), a first air inlet hole (14), a second air inlet hole (15) and a third air inlet hole (16). The photoelectric type comprehensive toxicity detector can well solve the problem of influence of environment temperature on detection precision.

Description

technical field [0001] The invention relates to an electronic instrument, in particular to a photoelectric comprehensive toxicity detector. Background technique [0002] With the rapid development of my country's economy, environmental pollution is becoming more and more serious. Various heavy metals and organic poisons such as mercury, chromium, and cyanide are discharged into natural water bodies such as rivers and lakes in large quantities, which has seriously threatened the safety of people's domestic water. Therefore, it is necessary and urgent to carry out safety inspection on drinking water. At present, the toxicity detection used for environmental monitoring generally adopts two methods: physical and chemical analysis and biological detection. A common toxicity detection method is physical and chemical analysis, that is, physical and chemical quantitative analysis of a certain harmful chemical substance. This method has high quantitative accuracy, but the detection...
