2021 China New Design Dahua Dome Camera 4k - Handheld liquid detector – Topsky

product description:
The hand-held dangerous liquid detector is a self-developed portable security detector specially designed for detecting flammable and explosive liquids. The technology has reached the international first-class level, and the performance of the product surpasses similar products of many international brands. It can effectively prevent dangerous liquids (liquid that can cause combustion or explosion) from entering the safe area.
The hand-held dangerous liquid safety detector is a security inspection instrument specially used to detect flammable and explosive liquids. Small size, fast analysis, simple operation, can quickly identify flammable and explosive liquids without contact with liquids, widely used in: transportation systems, logistics systems, government departments, embassies, police stations, fire stations, courts , Procuratorate, border defense stations, military, public places, large conference venues, stadiums, theaters, shopping malls, stations, subways, airports, public security inspections, government agencies, large-scale sports games and other crowded places.
It uses quasi-static computed tomography technology to determine its flammability and explosiveness by measuring the dielectric constant and conductivity of the liquid to be tested. The detector can distinguish liquid explosives, gasoline, acetone, ethanol and other flammable and explosive liquids from safe liquids such as water, cola, milk, and juice without direct contact with liquids. When using this method to detect liquids, the detection result has nothing to do with the size of the container where the liquid to be measured is located, and the air gap between the detector and the container will not affect the measurement result.
The handheld dangerous liquid detector is easy to operate. When using it, you only need to place the detector probe on the side of the container to be tested, the detection height is lower than the liquid level in the container, and then press the detection button. The green indicator light is on, and O and “safe liquid” appear on the display to indicate that the liquid in the container is safe; the red indicator light is on, X and “dangerous liquid” appear on the display, and an alarm sound is heard at the same time, indicating that the liquid in the container is easy Flammable and explosive. The detector does not contain ions, microwave radiation sources and other potentially dangerous elements, and is harmless to the safety of operators.
