Explosion-proof mobile phones have become more and more common in recent years, and the most common should be in gas stations. The equipment that the staff holds in hand is an explosion-proof mobile phone with intrinsically safe explosion-proof certification. With the rapid development of smart phones and the importance attached by various enterprises to safety precautions, the application of explosion-proof smart phones is becoming more and more widespread. Explosion-proof mobile phones are mobile phones that can be used in natural environments such as flammability, flammability, explosion, and smoke. Explosion-proof mobile phones are accompanied by Ex explosion-proof certification marks, indicating that the product has been verified according to the National Explosion-proof Testing Center, and can be used in special flammable gas natural environments, suitable for flammable and explosive sites in the petroleum industry, chemical plants, natural gas, etc. Explosion-proof mobile phones are actually processed by a technology that enables the machine itself to work and use in different environments. The explosion-proof level is based on the corresponding explosion-proof level in different environments. Intrinsic safety (EX) and coal safety (MA) certification are one of the explosion-proof levels. Intrinsically safe explosion-proof can be used in the petrochemical industry; and coal safety explosion-proof certification can also work normally in harsh environments such as coal mines and mines. CONQUEST S16 chemical explosion-proof mobile phone is an intrinsically safe explosion-proof mobile phone certified by the national professional testing agency. In the management of some dangerous goods, such as the chemical industry, the warehouse management and workshops of the chemical industry are also high-risk explosion areas, so it is necessary to equip scientifically and rationally with a control system, which can improve the utilization of resources according to the characteristics of the chemical plant itself , Adjust the production and operation behaviors, help the inspection of dangerous goods in compliance with the regulations, and ensure safety. In order to maintain the safety of chemical production, solve the common problems in daily inspection work, strengthen the number of effective inspections by inspection personnel, and prevent problems such as forged records, inadequate inspections, and failure to implement the system. Explosion-proof handhelds can be used in chemical management, which can effectively guarantee the work flow, and the inspection range limited to specific equipment, time, place and personnel can be preset by the system, which can meet the special inspections of various occasions and facilitate recording The time when the next staff arrives at the inspection point, equipment operation, parameters and other information.
