Nowadays, mobile phone signals are almost everywhere. While facilitating the use of mobile phones, the electromagnetic wave signals generated by them also affect other electrical equipment to a certain extent, especially the oil in gas stations, which has a certain potential safety hazard. At this time, the Signal Jammer plays a key role.

When the mobile phone battery is started at the gas station, the mobile phone rings, which will produce satisfactory energy and cause slight sparks. Meeting with inflammables such as oil in the air will lead to a fire, so we can see that there are written regulations in the gas station that prohibit the use of mobile phones in the gas station. According to the principle, the equipment of the gas station is controlled by the computer. The signal of the mobile phone will affect the normal operation of the equipment, which will lead to the prohibition of measurement. More importantly, when the mobile phone sends or receives high-frequency electromagnetic waves, there will be high-frequency current in it. If the mobile phone has poor contact, it will cause gas combustion, which will lead to the explosion of the gas station.

The use of Signal Jammer can limit the signals beyond 500m meters around, and the shielding radius is adjustable. The working area of Signal Jammer covers more than 30 ㎡. Mobile phones within this range cannot establish contact with signal towers, so the impact of electromagnetic signals emitted by mobile phone signals on gas stations can be avoided to a certain extent.
