Introducing our new explosion-proof DMR mobile radio designed to meet the needs of workers in hazardous working environments. This advanced mobile radio is built to withstand the harshest conditions, providing reliable communications and safety to workers in oil and gas, chemicals, mining, and other industries where explosive gases and dusts are present.


Explosion-proof DMR mobile radios are specifically designed to comply with international standards for use in potentially explosive environments, ensuring the highest level of safety for workers in these high-risk environments. The radio has a rugged construction and is explosion-proof certified to prevent explosions from any potential ignition source.


The radio is equipped with Digital Mobile Radio (DMR) technology for seamless, clear communication between workers, supervisors and the control room. It supports private and group calls, ensuring teams can always stay connected and coordinated. DMR technology delivers superior audio quality even in noisy and harsh environments, ensuring critical information is heard and understood without interference.


In addition to rugged design and advanced communication capabilities, explosion-proof DMR mobile radios offer a range of other advantages. It is intrinsically safe, meaning it is designed to prevent the release of enough electrical or thermal energy to ignite a specific hazardous atmosphere. This level of safety is critical for workers who often work in environments where explosive materials are present.


The radio also features long-lasting battery life, ensuring workers can rely on continuous communication throughout their shift. Its ergonomic design and intuitive interface make it easy to use, even while wearing gloves or protective gear. The large, high-contrast display is designed for use in low-light conditions, making it easy to read in any environment.


Additionally, the explosion-proof DMR mobile radio comes with a range of accessories to enhance its functionality. These include a remote speaker microphone, headset and vehicle mounting kit, allowing for flexible use of the radio. These accessories are also designed to be extremely durable and resistant to the same hazardous conditions as the radio itself.


Overall, explosion-proof DMR mobile radios are critical tools for ensuring the safety and productivity of workers in hazardous environments. Its reliable communications capabilities and rugged, intrinsically safe design make it a must-have for any team working in potentially explosive environments. With this radio, workers can rest easy knowing they are equipped with the highest level of safety and communications technology.


M4 is available in both DMR Tier 2 and analog modes, it supports AES 256 encryption keys to secure communication. Rugged and Reliable, IP68 ingress protection, the radio can use across multiple environments and industries.


M4EX Intrinsically Safe version is specially designed for those who work in environments with explosive gas and combustible dusts, providing secure and reliable voice and data communication in the dangerous areas.
