Chierda TC328DB explosion-proof radio is intrinsically safe, engineered specifically for workers in high-risk environments like chemical plants, coal mines, gas stations, oil companies, and fire stations. It meets the Ex ibIIB T4 Gb standard.
Digital and Analog Modes Combined
TC328DB is digital and analog modes combined. The radio can switch between digital and analog modes. In addition, it is repeater capable. You can pair TC328D with V9D digital repeater to extend battery life.
IP67 Fully Sealed Waterproof & Dustproof
TC328Db is certified IP67 waterproof and dustproof. It can remain fully functional even after being submerged in one meter of water for thirty minutes. Even in environments filled with corrosive gases or dust, the mainboard remains perfectly protected.
Average service life in heavy-duty industrial environments is extended by 20%.
Remote Monitor
When you are in digital mode and channels, you can push the programmable button to start the monitoring process. A single beep means start, and the handheld radio beep twice means the process ends. You can keep everything in total control.
SMS Function
TC328D DMR radio has SMS function and voice recording. With up to 500 hours of storage space, you can easily playback the recording.
VOX Hands-free
TC328D has VOX function to allow for hands-free operation. Once this feature is enabled, you can adjust the sensitivity level for triggering voice transmission.
