Tx vs Dx vs Basic UI Tier Decision
| Series | UI | Operator workflow | Premium vs basic |
| Basic (W3100A) | LCD | Numerical readout, simple mode buttons | — |
| Dx (W3101A) | Graphical Display | Multi-mode visualization, richer data display | ~$0 (essentially same price as basic; possibly newer-generation re-pricing) |
| Tx (W3102A — this product family) | Touch Screen | Touch-driven workflow, most-modern UI, on-screen multi-mode menus | +$427 over Dx |
Pick the Tx series (W3102A) when:
- Most-modern UI experience matters for the workflow / operator preferences
- Touch-screen interface supports faster setup vs button-based UI
- Multi-mode workflows benefit from on-screen menu navigation vs button-based navigation
- Multi-investigator facilities where touch-screen UI matches modern operator expectations
Pick the Dx series (W3101A) when graphical display is sufficient and budget-tier procurement is the priority ($427 saving vs Tx).
Pick the basic series (W3100A) when simple LCD numerical readout is sufficient.
