- • You need a 10.1″ screen for drawings, forms, or SCADA
- • Your organisation uses Samsung Knox or DeX

Choose IS930.1 if:
- • You need a compact, one-hand-holdable tablet

Screen Size: The Defining Difference
The Tab-Ex 03 DZ2's 10.1-inch display is its biggest advantage. For field engineers reviewing P&ID drawings, filling inspection checklists, or running SCADA dashboards, the extra screen real estate makes a measurable difference in efficiency. The ecom also supports Samsung DeX, allowing desktop-mode operation when docked.
The IS930.1's 8-inch display is a deliberate design choice — it's compact enough to hold in one hand while climbing ladders, working in confined spaces, or walking between process units. If your field workers primarily need a camera, barcode scanner, and simple data entry, the smaller form factor is an advantage, not a limitation.
Enterprise Management
The Tab-Ex 03 DZ2 is built on a Samsung Galaxy Tab Active, which means it inherits Samsung Knox — hardware-backed security, remote lock/wipe, and tight integration with Samsung's enterprise management tools. For organisations already running Samsung devices across offices and field sites, the Tab-Ex fits into the existing fleet.
The IS930.1 uses standard Android Enterprise, compatible with Microsoft Intune, VMware Workspace ONE, and other MDM platforms. It's more vendor-neutral but lacks Knox's hardware root of trust.
Price and Total Cost of Ownership
At approximately €2,400 vs €3,200, the IS930.1 is roughly 25% less expensive per unit. For a fleet of 50 tablets, that's a €40,000 difference in upfront cost alone. However, TCO depends on more than purchase price — consider accessory ecosystems, case replacement costs, and Samsung's typically longer software update commitment.

Bottom Line
The Tab-Ex 03 DZ2 is the better choice for inspection workflows, SCADA access, and Samsung-centric enterprises. The larger screen justifies the price premium when field workers spend hours reviewing documents and forms.
The IS930.1 is the better choice for mobile-first field workers who need a compact, lightweight device they can carry all day — and where budget matters. It's also the better fit for organisations that want a purpose-built Ex device rather than a modified consumer tablet.
