Professional Accuracy
Read any panel, curved or flat, with confidence
The NexPTG Professional's movable spherical probe and profiled housing maintain steady contact on door arches, bumpers and bonnets, eliminating the vibration-induced errors that trip up fixed-probe gauges on anything other than a flat door skin. One gauge covers steel, zinc-plated steel and aluminium - auto-detected every time.
Why NexPTG Professional
Built for the demands of professional inspection
Accuracy, coverage and documentation in one tool.
-
Auto Substrate Detection
Instantly identifies Fe, Fe+Zn and Al so you never need to switch modes between panels.
-
Live Bluetooth Data
Readings stream via Bluetooth 4.0 LE to iOS or Android as you probe, no manual logging.
-
Curved Surface Accuracy
Movable spherical probe eliminates vibration error on concave and convex body elements.
-
4 000-Point Memory
Store a full day's worth of readings across multiple vehicles before syncing to the app.
How It Stacks Up
NexPTG Professional vs. a typical entry-level gauge
Entry-level gauges get the job done on flat panels, but they leave gaps the moment the surface curves or the client asks for documentation. Here is where the difference shows up in practice.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Accurate readings on curved panels | Yes | No |
| Auto substrate detection (Fe/Fe+Zn/Al) | Yes | Yes |
| Bluetooth data transfer to smartphone | Yes | No |
| Exportable client inspection reports | Yes | No |
| Basic paint thickness measurement | Yes | Yes |
| Onboard memory for 4 000+ readings | Yes | No |
Workshop-Ready Reporting
From probe tip to client report in one session
With Bluetooth 4.0 LE, readings flow straight to the companion app on iOS or Android, where the SAPL Extended system maps them across the vehicle and flags deviations from factory norms. Walk away with an exportable report your client can read and trust, without a single number written down by hand.

Questions
Frequently asked
Which substrates does the NexPTG Professional detect?
The gauge automatically recognises three substrate types: steel (Fe), zinc-plated steel (Fe+Zn) and aluminium (Al). There is no need to manually select a mode - place the probe and the device identifies the substrate and applies the correct measurement method.
What is the measurement range and resolution?
The range is 0-2500 μm (0-98.43 mils) and the resolution is 1 μm (0.04 mils). That level of precision is more than sufficient to track factory paint depth, previous respray layers, and remaining clear coat before correction or PPF application.
How does the movable probe help on curved panels?
A fixed probe lifts unevenly on concave or convex surfaces, introducing vibration and angle errors. The NexPTG Professional uses a movable spherical probe tip combined with a profiled probe housing to maintain consistent contact on curved body elements - door arches, bumpers, bonnets - without the reading drift you get from a rigid setup.
How does the Bluetooth connectivity work?
The gauge pairs via Bluetooth 4.0 LE to the companion app on iOS or Android. Readings transmit wirelessly to the app in real time, where they are logged against suggested measurement points on a vehicle map. You can then generate and export a full inspection report directly from your phone.
How many readings can the gauge store?
The onboard memory holds up to 4 000 measurement items. This is more than enough for a multi-vehicle working day without needing to sync or clear data between jobs.
What is the SAPL Extended system?
SAPL Extended is NexPTG's lacquer coating analysis system built into the app. It uses your measurement data to analyse coating thickness across the vehicle, flags areas that deviate from factory norms, and guides you through suggested measurement point sequences to ensure thorough coverage and consistent reporting.
Can I export reports to share with clients?
Yes. The companion app lets you create a complete measurement history per vehicle and export it as a report. This is useful for pre-purchase inspections, insurance documentation, and showing clients the before-and-after state of a panel ahead of correction or coating work.
Is this gauge suitable for pre-correction and pre-PPF checks?
Absolutely - this is one of its primary use cases. Before compounding or wet-sanding, knowing the exact depth of the clear coat tells you how aggressively you can cut without burning through. Before PPF installation, confirming bare or previously resprayed panels prevents warranty issues later. The 1 μm resolution gives you the confidence to make those calls accurately.
