Delta aPAT Pro Print Pack Review

Pro Print PackPros: Great value for a fully wireless test and tag solution with printer, scanner and high-end software. Seamless data syncing with custom branding, re-testing alerts and multi-database management.

Cons: The aPAT software is only compatible with Android devices (Apple isn't supported). If transferring data to your PC, some of the fields (such as comments) will not transfer across.

The Bottom Line: If you're looking for a complete, streamlined test and tag setup, the Delta aPAT Pro Print Pack remains one of the most efficient and powerful all-in-one solutions on the market. This Test & Print Kit is wireless, customisable, and designed for serious professionals. While it’s best suited for users with some technical confidence, the time-saving benefits and seamless workflow make it a smart long-term investment.

Key Features of the Delta Pro Print Pack

The Delta aPAT Pro Print Pack continues to lead the market in 2025 as one of the few truly wireless test and tag kits available. It’s built around the rock-solid DeltaPAT 3309 BT tester and powered by the advanced aPAT Android software, delivering a high-end test and tag experience with unmatched flexibility and efficiency.

Where other kits rely on USB transfers and manual data entry, the Pro Print Pack offers real-time syncing, on-the-spot printing, remote control functionality, and streamlined retesting workflows. If speed and automation matter to your business, this kit is in a league of its own.

Built for Portability, Designed for Speed

Included in the kit is the Zebra ZQ521 Bluetooth printer - a compact, rugged unit that prints Direct Thermal tags with clarity and durability. It’s built to survive tough job sites, with excellent battery life and easy Bluetooth pairing. 

All components fit neatly into a hard carry case for on-the-go test and taggers who need to work across multiple locations, particularly in construction, mining, and facilities management.

aPAT Software - The Real Game Changer

What sets this kit apart is the aPAT app, which connects your Android device to the tester, printer, and scanner - creating a complete ecosystem. It minimises your workload and helps customise the way you work.

  • Custom test parameters
  • Instant test result syncing
  • Real-time compliance tracking
  • Retesting reminders and scanning
  • Automatic report generation
  • Custom tag branding (up to 4 logos)

Whether you're testing 50 items or 500, the aPAT workflow makes it faster, cleaner, and more professional. The app supports multiple databases, ideal for people testing and tagging multiple clients or job sites.

Important to note: an Android device with autofocus is essential. If you don’t have one already, a compatible tablet or phone can be picked up for under $250, and it's well worth the investment.

Firmware update 2025: Metrel released a firmware update for the DeltaPAT 3309 BT, significantly improving Bluetooth connectivity and printer pairing - particularly with the Zebra ZQ521 used in this kit. This update reduces connection dropouts and ensures a more stable and seamless wireless workflow. If you’ve used older setups before, the latest firmware makes a noticeable difference.

How it Performs in the Field

The Delta Pro Print Pack shines in high-volume testing environments where speed, accuracy, and compliance are critical. Users across construction sites, mining facilities, and large-scale commercial operations benefit from the fully wireless workflow - especially the ability to:

  • Scan barcodes or QR codes for instant access to test history
  • Remotely control the tester from an Android device
  • Enter data and photos in real time
  • Sync and send results to the office without retyping anything
  • Create custom test paramaters and shortcuts

The biggest learning curve is the aPAT software interface - it’s not difficult, but it does require a brief setup and familiarity with Android workflows. Once in place, the efficiency gains are significant.

This kit eliminates unnecessary paperwork, speeds up re-testing, and allows your team to work smarter, not harder.

Drawbacks to Consider 

  • Android-Only Compatibility: as mentioned previously, you must use an Android phone or tablet with autofocus to access aPAT’s full functionality. Apple devices are not supported.
  • PC Sync Limitations: some fields like the “comments” section do not currently sync to PC reports - though Metrel has confirmed a software fix is on the way in 2025 to resolve this issue.

Is it Worth the Investment?

While the Delta Pro Print Pack is the most expensive kit on our Top 5 PAT Testers of 2025, it offers the highest return in productivity and justifies its #1 position.

By removing manual entry, enabling wireless syncing, and automating the full test and tag workflow, it allows users to complete more jobs, more accurately, in less time - and that pays off fast for anyone working in volume.

If you're a solo trader, business owner, or safety manager looking for full control, speed, and compliance in one kit, this is the best all-in-one solution on the market in 2025.
