Magic Dangerous Liquid Detector

First of all, we will understand that the dangerous liquid detector is based on the principle of microwave detection, which will not cause harm to human body like X-ray and other radioactive chemical substances. It is a security inspection instrument specially used to detect flammable and explosive dangerous liquid. There are many dangerous liquid detection technologies in the world, such as Raman spectroscopy, which emits a beam of light to the liquid to scatter. According to no way The spectral characteristics reflected by substances can be used to distinguish the types of liquids, which are applicable to food, agriculture, animal husbandry, pharmaceutical and medical, criminal investigation and jewelry industries. The dangerous liquid detector adopts quasi-static CT technology. The detector can distinguish the flammable and explosive liquid such as liquid explosive composition, gasoline, acetone, ethanol and water from the safe liquid without direct contact with the liquid, and can quickly identify them in a short time of one second. It is suitable for transportation, government, large meeting places and other departments.
At present, the most widely used subway and station in China is the quasi-static electrical tomography, which is called "quasi-static computer tomography". By measuring the dielectric constant and conductivity of the liquid to be tested, it can judge whether the liquid is flammable and explosive. The dielectric constant and conductivity of safe liquid and dangerous liquid are quite different.
This technique can measure the spatial distribution of the electronic properties of a medium, so the properties of the liquid can be determined regardless of the material of the container. Air gap is allowed between the device and the container. Then, the electronic characteristics (dielectric constant and conductivity) of the liquid will determine whether the liquid is flammable or explosive. At the same time, the equipment is completely electronic, and does not contain any radioactive and microwave materials and other potentially dangerous components.
The detector does not need any adjustment and preparation work, and the operation is very simple. Hold the device, place the sensor close to the surface of the container to be tested, keep it lower than the surface of the liquid, and press the button. If the indicator light is green, it indicates that the liquid in the container is non combustible. If it is red, the liquid is dangerous. If the yellow light is on, it indicates improper operation, correct the operation posture and retest.
The use of dangerous liquid detector will be conducive to liquid security inspection, strictly control the public security hazards caused by suspected dangerous liquid, and also help to speed up the security inspection and shorten the security inspection time. Because it has the characteristics of fast detection speed, simple operation and convenient carrying, so it is the place where dangerous liquid detectors display their skills in stations, airports, subways, courts, customs, etc.
