PT790-Ex
Unieke code: PT790-Ex

De PT790 Ex is de eerste portofoon met de zwaarste ATEX certificering van de wereld. Deze portofoon is getest op het “ia” level. De robuuste constructie en zijn veiligheidsfuncties zorgen voor ideaal gebruik bij gevaarlijke omgevingen zoals de olie en gas industrie.

For many experts 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 PT790 Ex handheld radio offers first-class protection to the user, who are depending on reliable TETRA radio in such explosive or flammable areas. As the globally first TETRA radio with "ia" approval, the PT790 Ex meets the highest demands that can be placed on an intrinsically safe product.

Maximum safety
Thanks to its "ia"-approval, the PT790 Ex can be used in areas where an explosive atmosphere with a mixture of air and flammable gases, vapors or mists is permanently present (zone 0).

Robust and reliable
Even under harsh operating conditions the PT790 Ex provides outstanding performance. The handheld radio is dustproof and waterproof according to IP67 and may be immersed for at least 30 minutes in a water depth of 1 meter. The PT790 Ex also meets the requirements of the US MIL-STD-810 F/G-standards.

Features for work safety
In order to provide the maximum possible safety at work, the PT790 ex provides 'man down' and an adjustable time alarm (lone worker function). The GNSS module comes as standard and collects position data via GPS, GLONASS, and Beidou. This data can be transmitted to control centers / dispatchers with AVL for further analysis.

Immediate and direct TETRA communication
The PT790 Ex offers fast access to the TETRA mobile radio network and its services. Moreover, it meets the requirements of the ETSI TETRA standard and is therefore compatible with infrastructure and terminals from different manufacturers.

Versatile features
In addition to voice and data communications, the PT790 Ex provides many more features: encryption, programmable keys, etc. In addition, the handheld radio has an interface for extensions and accessories.
