Security artifact—handheld dangerous liquid safety detector

　　In order to prevent dangerous liquids from being brought into public places,especially liquid explosives are brought into carriages and stations,causing heavy casualties,many countries pay more and more attention to the safety inspection of liquids.

　　Usually at train stations,subway entrances,and museum entrances,when passing through the security check,if you bring drinks or mineral water with you,you will be stopped by the security inspector and asked to"take a sip"or not allow liquids to be brought in.This seemingly effective method actually has no way to avoid potential safety hazards.For example,it is difficult to identify alcohol.Because traditional security inspection equipment is difficult to identify liquid explosives,there are great hidden dangers to public safety.

　　That is why the dangerous liquid detector came into being.It is able to quickly solved the problem that the dangerous liquid is difficult to detect.

　　The dangerous liquid detector can perform safety inspection on the liquid in the non-metallic device.It is a security inspection instrument used to detect flammable and explosive liquids.It uses quasi-static computer tomography technology to measure the dielectric constant and conductivity of the liquid to be tested to judge its flammability and explosiveness.The detector can distinguish gasoline,acetone,ethanol and other flammable and explosive liquids from safe liquids such as water,cola,milk and fruit juice without directly contacting the liquid.Not only the air gap between the detector and the container will not affect the measurement results,but also the dangerous liquid detector has no special requirements on the material,color and transparency of the packaging.As a result,liquid items packaged in plastic,glass,ceramic,metal and other material containers can be safely detected without any impact or damage to the liquid items in the container.

　　In addition,It is absolutely easy to handle the dangerous liquid detector.Put the detector on the side of the container to be tested,then press the button.When the red light is on,the display screen will appear the word of danger and there will be an alarm sound at the same time.That means that the liquid in the container is flammable and explosive.However,when the green light is on and the word of"safety"appears on the display.That means the liquid in the container is safe.More important,the hazardous liquid detector is very safe and harmless to the operator.
