Nowadays, more and more cars are used. In the process of queuing for refueling, it is often seen that people in the car answer or make calls. Despite the "no cellphone" signs at gas stations, many drivers are unaware of the danger.
During the refueling process of the vehicle, the oil and gas will diffuse and volatilize outward, causing the gasoline density around the vehicle to increase sharply. Especially in summer, the temperature is high, gasoline volatilizes faster, and once it reaches the corresponding concentration, any small sparks or static electricity will cause an explosion. At present, none of the mobile phones on the market have explosion-proof function. If you take a call at this time, the phone will explode as soon as sparks are generated due to electronic friction.
The electromagnetic signal intensity emitted by the radio frequency jammer is very weak, and its electromagnetic radiation intensity has been tested by the national authoritative testing and certification organization. All products produced are qualified and will not cause harm to the human body. The power of the wireless wifi bluetooth jammer is very small, and the frequency of the electromagnetic signal emitted is within the specified working frequency band, which will not affect other electronic equipment, and will not affect the safety of the gas station, which is safe and reliable.
Therefore, it is very important to install a wireless wifi signal jammer at the gas station, so that the mobile phone loses the signal before entering the gas station, and controls some of the phenomenon of receiving and calling mobile phones at the gas station.
