Hytera PD795 Ex - ATEX Radio

The first digital IIC intrinsically safe DMR handheld radio in the world encased in a plastic housing and IP67 degree of protection.

    Product description

    The PD795 Ex handheld radio from Hytera meets the open ETSI DMR standard. Compliance with European ATEX directives, FM standards, IEC standards, and its outstanding robustness ensure reliable communication in dangerous environments, such as those containing explosive gases and combustible dust.

    Highlights – durability

    The PD795?Ex handheld radio complies with all the requirements of the European ATEX directives, IEC guidelines and the North American FM standard. Furthermore, the terminal meets the MIL-STD-810C/D/E/F/G standard and is dust-proof and waterproof in accordance with degree of protection IP67. The PD795?Ex is therefore ideal for secure and reliable use even in potentially dangerous conditions.

    ATEX certification

    All radios used in potentially explosive environments must comply with the European Union's ATEX directives.

    The PD795 Ex meets the following ATEX directives:

    • ATEX Gas Protection: II 2 G Ex ib IIC T4
    • ATEX Dust Protection: II 2 D Ex ib IIIC T120 °C
    • ATEX Protection for Mining Application: I M2 Ex ib

    Fail-safe design

    The use of batteries or accessory components with a lower level of protection automatically triggers an alarm so that errors of this type cannot occur.

    Plastic encapsulation

    Both the radio and the battery are encased in a plastic housing to ensure that all internal connections are protected and sealed off from dangerous explosive gases and dust particles.

    High-strength LCD protective cover

    The high-strength LCD protective cover is extremely scratch-resistant and would even withstand being struck by a 1-kg hammer.

    Innovative battery latch

    The patented lock of the battery ensures that the battery cannot fall out if the radio should be dropped onto a hard surface.

    Integrated GPS as standard

    Using the integrated GPS module, the PD795 Ex can send location information to dispatcher systems. Dispatchers can evaluate this information and use functions such as geofencing, radio localization and GPS tracking.

    Upgradeable software

    The upgradeable software makes the use of new features possible. By altering the firmware-software, other digital and analog operating modes can be enabled, without the need for purchasing a new radio device.
