Explosion proof mobile phones, a niche product in the industry, do not need to focus on brands. Unlike consumer electronics giants such as Apple, Samsung and Huawei, they are basically made in Shenzhen, China, focusing on integration. The so-called Huawei explosion-proof mobile phone is also artificially modified by a third party on the consumer Huawei mobile phone. Therefore, the choice of explosion-proof mobile phone depends on the cost performance, as follows:
Explosion proof certificate
Generally, they are classified into intrinsically safe type and flameproof type. Most of them are not used in closed places, such as gas stations and chemical plants. Intrinsically safe type is sufficient for Zone 1 and Zone 2, but not Zone 0. Generally, regular explosion-proof mobile phones will have explosion-proof certificate number such as IIB IIC T5 on the body, and each phone will also have an explosion-proof certificate.
Explosion proof mobile phones are also mobile phones, so the state has stipulated that communication products must have a network access license, 3c, and radio approval certificate. 3c is a compulsory national security certification to ensure your basic security. The network access license is also a necessary qualification for sales in all channels, which will attract the inspection of the Administration for Industry and Commerce anyway
Explosion proof mobile phones are basically used for work, so we will definitely choose the three prevention, at least IP68 level, which can be waterproof and fall proof, so we can be confident when working; The higher the CPU chip is, the better it is; The memory is generally 2+16G, 3+32G, 4+64G, 6+128G, depending on your needs. Of course, the larger the better; You can't have both battery capacity and light basic fish and bear's paw. Personally, you will charge every day no matter how big the battery is, you know!
This must be the top priority. It is better to choose large platforms to purchase as much as possible, and it is better to have three parties monitor. Or it is better to be bound by the contract.
