Intrinsically Safe TETRA Two Way Radio
For many workers, two-way radios represent an indispensable tool in their day-to-day work. For those working in environments containing explosive gases, combustible dust, or in the mining industry, safety is of particular importance, the intrinsically-safe handheld Hytera PT790 Ex radio offers first class protection for users who are dependent on reliable TETRA radio technology.
The robust construction and in-built safety features improve the security of Atex users from industries such as oil and gas, mining and fire rescue.
IA Safety of the highest level Device groups
The PT790 Ex is the world’s first TETRA handheld two-way radio with the highest intrinsic safety level “ia”.
The operating resources employed in the potentially explosive area contain only intrinsically safe circuits. A circuit is considered intrinsically safe if no spark and no thermal effect that occur under defined testing conditions, can cause the ignition of a specific explosive atmosphere.
Enhanced Speech Processing Technology
Hytera PT790Ex adopts state-of-the-art speech processing technology to remove environment noise (ambient noise) and echo (acoustic&echo), which provides users with clear voice communication even in a noisy environment. Meanwhile, it has better performance in hands-free mode in full duplex call.
Strict PCB Design & High EMC Performance
To achieve high explosion-proof level, Hytera PT790Ex adopts optimal PCB layout design. All the key components of PCB are covered with shield which minimizes the circuit fault probability and has better performance of EMC.
Patented Battery Latch Design
To disengage the battery from the radio, you need to remove the lock and bolt of the latch along two different axes. Such a patented design ensures there is no disengagement of the battery pack from the main radio in case of dropping that might cause spark.
The built-in GNSS module supports GPS, GLONASS, Beidou. Its tracking sensitivity is up to -164dBm, and its accuracy is within 2 meters.
When a user falls down, the radio can automatically alert others.
To ensure the safety of terminal users, the emergency function will be triggered automatically when there is no operation on the terminal within the predefined time period.
Long Cycle Life
Hytera PT790EX provides 1800mAh/2400mAh large capacity Li-ion battery, which can last for more than 20 hours under 5-5-90 duty cycle. Strict overcharge and overdischarge protection design ensure the battery against instability caused by overheating. In addition, the battery cells are also encapsulated to redistribute single point heat buildup and prevent air discharge as well.
Rugged & Reliable
PT790Ex is designed to comply with MILSTD 810G and IP67 Dust&Water Protection Rating, which ensures its best performance even in the toughest conditions and environment.
Hytera PT790Ex enables quick access to TETRA network and roaming, providing safe and efficient communication service. It also provides powerful interoperability with base stations and terminals of different manufacturers.
