A thermal imaging smartphone, a phone with physical keys and an 8-inch rugged tablet: Phonemax brought three different approaches to professional mobility to Expoprotection 2026 in Paris.
Held from 3–5 November at Paris Expo Porte de Versailles, Hall 1, the exhibition gave our team an opportunity to meet occupational safety industry professionals and buyers looking for equipment to support their work. The Phonemax display included the R4 GT, F4 T and T1, covering specialised imaging, everyday communication and field documentation.
Meeting Occupational Safety Professionals in Paris
Visitors to the Phonemax display mainly included people working in the occupational safety sector and those sourcing products for related needs.
At the counter, our representatives reviewed product information with visitors alongside the displayed devices. One photograph captures a catalogue discussion beside rows of phones and tablets; another shows our team presenting the lineup behind the Phonemax-branded counter.
For these buyers, the display offered a direct look at different device formats. The compact R4 GT, physical-keypad F4 T and larger-screen T1 provided concrete starting points for discussing equipment requirements.
R4 GT: Thermal Imaging and Infrared Night Vision
The Phonemax R4 GT thermal imaging smartphone combines a 256 × 192 thermal camera with a separate 20MP infrared night-vision camera in a compact body.
For equipment inspection, thermal imaging helps users locate temperature differences on accessible surfaces. Maintenance personnel can use it to examine unusual heat patterns around electrical components or compare temperatures along exposed pipework, then investigate the findings using appropriate procedures.
Its infrared-assisted night vision captures scene detail in darkness. This serves a different purpose from thermal imaging: one helps users see the scene, while the other visualises temperature differences.
The R4 GT has a 4.3-inch display, a 3200mAh battery and published IP68/IP69K protection ratings. Its product specifications also list MIL-STD-810H.
Thermal images support investigation; they do not establish the cause of a fault, reveal objects through walls or replace safety-critical measurement equipment.
F4 T: Physical Keys with Android Touchscreen Operation
The Phonemax F4 T Android keypad phone brings physical controls and touchscreen operation together in one device.
Its 3.3-inch touchscreen supports interaction with compatible Android applications, while the keypad provides button-based handling for users who prefer physical controls. A 5000mAh battery supports its communication-focused design.
For teams selecting phones for routine calls and messaging, the F4 T offers a different interface from a touchscreen-only smartphone. Required applications should be checked on its Android 9 platform before deployment.
The EU/Asia and US/Americas versions have different mobile-band configurations. Buyers should confirm the correct version and carrier support for the country where the phones will be used.
T1: An 8-Inch Rugged Tablet for Field Documentation
The Phonemax T1 rugged tablet added a larger-screen option to the exhibition display.
Its 8-inch screen provides more space for inspection forms, work orders, maps and technical documents. For field personnel moving between locations, that format supports reviewing instructions and entering information without returning to a desk.
The T1’s published specifications include a 12,000mAh battery and IP68/IP69K protection. Actual operating time depends on applications, screen brightness, connectivity and working conditions.
T1 configurations differ. The current grey model is listed with Android 16, 6GB RAM and 128GB storage; buyers should confirm the exact operating system, memory and accessory requirements when selecting a configuration.
Three Devices, Different Priorities
| Feature | R4 GT | F4 T | T1 |
|---|---|---|---|
| Device format | Compact rugged smartphone | Android touchscreen keypad phone | Industrial rugged tablet |
| Display | 4.3-inch | 3.3-inch | 8-inch |
| Battery capacity | 3200mAh | 5000mAh | 12,000mAh |
| Key capability | 256 × 192 thermal imaging and separate 20MP infrared night vision | Physical keypad with touchscreen operation | Larger screen for field applications and documents |
| Published protection | IP68/IP69K; MIL-STD-810H listed | Confirm requirements with Phonemax | IP68/IP69K |
| Example application | Investigating surface temperature differences during maintenance | Routine calls and compatible communication applications | Inspection forms, work orders and technical reference |
Specifications above describe the published product range, rather than every configuration displayed at the exhibition. Protection ratings relate to controlled test conditions; wear and damage can reduce protection.
