Field technicians operating in ATEX Zone 1 and Zone 2 classified areas require hardware that matches their specific operational tasks. Whether reviewing complex P&ID engineering schematics, signing off on electronic Permit-to-Work (ePTW) forms, or referencing real-time telemetry, display real estate is essential for reducing errors.
While ATEX-certified industrial tablets remain the benchmark for detailed engineering work, dense data entry, and stationary field stations, large-format smartphones—such as the 6.9-inch iPhone Pro Max housed in an Atexxo explosion-proof enclosure—offer an agile, pocketable alternative for high-mobility field inspections.
At Atexxo Manufacturing, we help enterprise IT and safety teams equip their personnel with the exact form factor required for their daily workflows.
Defining the role of ATEX tablets in plant operations
Industrial tablets serve an essential role in digital plant management. For workflows that demand maximum screen area, a tablet is often the most productive tool for the job.
- Complex schematic analysis: Reviewing multi-layered CAD drawings, piping schematics, and detailed process flow diagrams is significantly easier on an 11-inch canvas, minimizing constant zooming and panning.
- Stationary and vehicle-mounted workstations: Tablets excel when mounted in maintenance vehicles, crane cabs, or temporary field engineering desks where continuous mobility on foot is not required.
- Dense data entry: Filling out extensive multi-page compliance audits or operating complex enterprise software dashboards benefits from the larger virtual keyboard and side-by-side app multitasking that tablets provide.
The pocketable alternative for agile field mobility
For technicians who spend their shifts constantly on the move—climbing vertical ladders, squeezing into vessel crawl spaces, or walking miles of pipe racks—carrying a larger tablet is not always practical.
This is where large-screen smartphones like the 6.9-inch iPhone Pro Max enclosed in an Atexxo ATEX/IECEx Zone 1/21 case bridge the gap between mobility and visual clarity:
- Hands-free agility: When a technician needs both hands to adjust a valve, pull a chemical sample, or operate a gas detector, an Atexxo-enclosed smartphone slides directly into a work-suit pocket.
- Pro-grade optical diagnostics: Modern Pro smartphones incorporate 48MP primary sensors, optical telephoto lenses (up to 5x native zoom), and integrated LiDAR. Technicians can capture pin-sharp macro photos of corroded valve tags from a safe distance without bringing extra camera gear into the unit.
- Desktop-class edge computing: Apple’s A-series Pro processors feature powerful neural engines, enabling field crews to run localized, offline AI models (such as Google Gemma 4) and 3D spatial scans natively without system lag.

Matching hardware to specific site roles
Rather than forcing a single device type across the entire workforce, modern facilities achieve the highest return on investment by deploying a hybrid hardware strategy:
| Operational role | Recommended form factor | Key operational advantage |
| Field Maintenance Inspector | Atexxo Zone 1 iPhone Pro Max | Pocketable, hands-free climbing, 5x optical zoom for distant valve reads |
| Plant Reliability Engineer | ATEX Industrial Tablet | Expansive display for detailed P&ID analysis and complex CMMS data entry |
| Turnaround / Contractor Crew | Atexxo Zone 1 iPhone Pro Max | Zero learning curve (iOS), fast ePTW sign-offs, integrated LiDAR |
| Control Room Operator / Specialist | ATEX Industrial Tablet | High screen real estate for multi-variable telemetry monitoring |
By pairing Atexxo explosion-proof enclosures for mobile smartphones alongside certified industrial tablets, operators ensure that every worker has the exact tool needed to maintain safety and productivity.
Frequently asked questions
Are ATEX tablets still recommended for Zone 1 hazardous areas?
Yes. ATEX tablets remain the preferred choice for roles that require viewing large engineering drawings, conducting complex static audits, or managing multi-window enterprise applications where maximum screen real estate is essential.
How does a 6.9-inch smartphone compare to a compact tablet for field work?
A 6.9-inch display (like the iPhone Pro Max) provides sufficient visual space for roughly 90% of routine field tasks—such as viewing ePTW forms, checking asset tags, and capturing photos—while remaining light enough to fit inside a standard work-suit pocket.
Can Atexxo Manufacturing convert both smartphones and tablets for hazardous areas?
Yes. Atexxo Manufacturing specializes in engineering certified explosion-proof conversions for flagship consumer smart technology, allowing industrial facilities to deploy both smartphones and tablets safely into ATEX and IECEx classified zones.
