PD795IS Intrinsically-safe digital two-way radio


Handheld ATEX | DMR

Offering safe, reliable communications, the Hytera PD795IS handheld digital two-way radio with screen and full keypad has been designed to comply with the highest 'ia' standards making this the ideal communication solution for working environments that require advanced, intrinsically-safe devices.

Highlights of PD795IS


Send a priority transmission to interrupt other calls, ideal for important, critical messages.


Using pseudo-trunking, a Hytera patented technology, slots can be shared to improve capacity usage with transmissions either direct to handset or to repeater.


Combining noise cancelling technology to remove nusiance noise from the transmission, with powerful speakers to deliver clear communications.


Enabling location based services to improve safety and control.


This feature allows the radio to switch between sites on Multi-site Conventional and XPT systems, ensuring seamless communication.


Raise an alarm with top priority to a base station or to other radios with the pre-programmed emergency mode, identifying the ID of the person issuing the alarm. Also receive emergency notifications.

GPS Location

Positioning and tracking as standard, also including man down feature

Rugged and Reliable

Dust and waterproof, rated IP67, sustaining performance in harsh environments

Ergonomic Design

Separate functions and large textured keys intelligently positioned to enhance operation accuracy

Innovative Construction

Silicone encapsulated technology helps prevent the internal circuits from being damaged by intrusive liquid, inflammable dust and explosive gases

Clever Design

PD795IS display and shell adopt anti-static design from the dual material moulding technology, resulting in a reduction in the static discharge on the radio
