The PT790 Ex is the first TETRA handheld radio worldwide with the highest intrinsically safe level "ia". Its robust design and its safety functions substantially increase the industrial safety of users in the oil and gas industry, mining industry or fire departments. As the first TETRA handheld radio throughout the world with "ia" approval, the PT790 Ex can be used in areas in which an explosive atmosphere containing a mix of air and combustible gases, vapors or mists are permanently present (Zone 0). In addition, the radio can be used in areas where hazardous materials are only present under certain circumstances/conditions (Zone 1).
