Description:
Product features are flammable dust explosion-proof, to meet the needs of different groups of users to communicate, improve work efficiency.
Explosion-proof walkie-talkie refers to the walkie-talkie that can work in dangerous gas environment.
Different from the civilian walkie-talkie, the walkie-talkie relys on electromagnetic wave to transmit signals. In the process of conversion, it is easy to generate electric sparks, while the places where the explosion-proof walkie-talkie may generate sparks in the process of conversion are shielded, and the performance of the walkie-talkie is higher under special circumstances, and the conversation is clearer and brighter.
