Product features are flammable dust explosion-proof, to meet the needs of different groups of users to communicate, improve work efficiency.
An explosion-proof walkie-talkie refers to the walkie-talkie that can work in a dangerous gas environment. Different from the civilian walkie-talkie, the walkie-talkie relies on electromagnetic waves 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
