Motorola GP340Ex — ATEX Zone 1, 16 Channels, 1,800mAh at 290g
The intrinsically safe workhorse for explosive atmospheres: ATEX Zone 1 certified for gas and dust hazardous areas, 16 channels, 1,800mAh battery with 14-hour runtime, and a 290g chassis built for hot-zone duty. Where the GP340Ex earns its place: oil refineries, gas plants, chemical processing, and mine sites with explosive-risk zones — areas where a standard radio's spark could be a fatal incident. The 16-channel limit is the trade-off for certification; in a hazardous zone, compliance is not optional, and the GP340Ex is the radio the safety case requires.
Hytera HP705 — 256 Channels, GPS, IP67, 22-Hour Field Team Radio
The general-duty field team radio: 256-channel capacity across multiple zones, integrated GPS for dispatch visibility, IP67 dust/water protection, and a 22-hour battery carrying full-shift operations — 8 hours beyond the GP340Ex. DMR Tier II dual-slot TDMA. For mine and plant sites, the deployment pattern is complementary: HP705s cover the general operational area where spark risk is managed, while GP340Ex units are issued only for the certified hazardous zones — keeping fleet cost down without compromising the safety case. The HP705's 22-hour envelope and GPS visibility suit the wide-area field crews that make up the bulk of any site.
