Extreme 5G PRO | 5G Intrinsically Safe Smartphone

The Extreme 5G PRO is a CCRI-certified intrinsically safe 5G smartphone built for professionals working in explosive hazardous environments, including marine, offshore, oil and gas, petrochemical, construction and industrial sites.

Unitech Supplies is Dorland’s official distributor for Singapore and Southeast Asia, so every Extreme 5G PRO sold here is genuine, certified stock — with Ex ib IIC T4 Gb / Ex ibD 21 T130℃ protection for Zone 1 and Zone 2 hazardous areas.

Key Benefits

  • All-day power for long shifts — 8500mAh battery keeps field teams connected through extended operations
  • Fast enough for real fieldwork — 12GB RAM and 256GB storage (expandable to 2TB) handle inspection apps, reporting software and photo/video documentation without lag
  • Built for harsh conditions — IP68-rated against dust and water, rated for operation from -20°C to +60°C

Description

Why It Stands Out

The Extreme 5G PRO pairs full intrinsic safety certification with the everyday usability of a modern Android smartphone, so field teams don’t have to choose between staying compliant and staying connected. It’s certified Ex ib IIC T4 Gb / Ex ibD 21 T130℃ under CCRI 21.2841, meaning it’s approved for use in Zone 1 and Zone 2 explosive hazardous areas where standard consumer devices simply aren’t permitted — and where an unsuitable phone can pose a real safety risk on site.

Under the hood, the Dimensity 6300 processor and 12GB of RAM keep the phone responsive for the kind of work it’s actually used for: running inspection and work-permit apps, pulling up drawings and reports, and staying on video calls or messaging platforms without the lag that older rugged devices are known for. With 256GB of onboard storage and support for microSD cards up to 2TB, there’s plenty of room for photo documentation, technical files and site records.

The 8500mAh battery is sized for the reality of offshore and industrial shifts, where charging points aren’t always nearby. An IP68 rating and a -20°C to +60°C operating range mean the phone is built to keep working through dust, rain, humidity and temperature swings that would put a regular smartphone out of action. When something does go wrong, the programmable custom key can be set to trigger an SOS alert with a single press, without needing to unlock the phone or dig through menus.

Who It’s For

  • Marine & offshore — vessel crews, engine room teams, ship inspectors, port operations staff
  • Oil & gas — offshore platform and FPSO personnel, drilling operations, refinery maintenance teams, shutdown and turnaround crews
  • Construction & industrial — site supervisors, plant maintenance personnel, facility management and utilities teams
  • Petrochemical & pharmaceutical — chemical manufacturing facilities, tank farms, storage terminals, production environments requiring intrinsically safe equipment
  • Security & general field use — safety officers, inspection engineers, surveyors and emergency response personnel working in or near hazardous areas
