GP340Ex — ATEX Zone 1 Analog with 16 Channels, 1,800mAh, and 14-Hour Runtime at 290g
Explosion-proof portable certified ATEX Zone 1 — explosive gas present during normal operation. 16 channels of pure analog operation: explosion-proof certification isolates every electronic path, so digital feature complexity is deliberately traded away for intrinsic safety. 1,800mAh battery delivers 14 hours at 290g. The established hazardous-site workhorse in chemical plants, gas processing, and oil tank farms across Asia and the Middle East, where legacy analog fleets and lower unit cost keep GP340Ex the default zone-entry radio. Procurement logic: minimum viable certification compliance at the lowest cost per unit — the radio's job is to be intrinsically safe and legally present, not feature-rich.
MTP8550Ex — TETRA ATEX/IECEx Zone 1 with Class 3L 1.8W, TEA End-to-End Encryption, and 16-Hour Runtime
TETRA portable with dual ATEX and IECEx Zone 1 certification — the highest safety tier available, with Class 3L 1.8W adaptive RF output that self-regulates in hazardous zones. TEA end-to-end encryption secures voice and SDS data from terminal to terminal — impossible on the analog GP340Ex. Gateway/repeater mode extends coverage without additional infrastructure. 1,850mAh Li-Ion battery delivers 16 hours — two hours beyond GP340Ex despite running a digital trunking protocol. The premium choice for refinery complexes, LNG terminals, and offshore platforms where digital trunking, encrypted mission-critical comms, and IECEx international certification justify a 3-4x price premium over analog zone radios.
