Decision
A compact USB-C attachment for switching between supported iOS and Android phones.
Choose TOPDON TC002C Duo for a compact USB-C thermal attachment that works with supported iOS and Android phones. Skip it if you need a detached wireless head or a self-contained screen. No guide-author hands-on testing was performed. Two hands-on reviews are available, but exact-model community consensus was not established.
Specs
Native detail and workflow fit matter more than a headline pixel number.
The native detector is 256 × 192; TISR output of 512 × 384 is processed resolution. TOPDON lists 25 Hz imaging, a −20 to 550 °C range and USB-C iOS, Android and Windows compatibility.

Workflow
Test the exact connection and inspection workflow.
Test the exact phone, USB-C connection, case clearance, and inspection workflow during the return window. Duo describes platform support, rather than two imaging sensors. Two hands-on reviews provide setup context, but exact-model community consensus is not established. The manufacturer page showed $299 when checked, while availability signals conflicted, so confirm current stock.
Interpretation
Use thermal images to locate questions.
A thermal image shows surface-temperature patterns. Reflections, emissivity, distance, and angle can mislead. Use it to decide where to investigate next; do not describe it as seeing through walls or as a diagnosis.
Reviews
Reviews set expectations; they do not become a lab ranking.
Home inspector Reuben Saltzman found the app useful but reported case clearance/port strain and saved-image orientation friction. Tested software and handset only; absence of MSX-like fusion does not mean absence of a phone-camera inset. The Gadgeteer found quick setup, no required account in the tested version and useful phone-camera picture-in-picture documentation. Tested on iPhone 16 Pro Max; no traceable temperature calibration study.
Alternatives
Choose the form factor around the job.
Edge Pro buys detached camera positioning; TC002C Duo and Mini2Plus V2 keep the phone as display; Nano 300 offers higher native pixel count but requires an exact connector; FLIR C5 is self-contained. Choose around inspection geometry and phone constraints.
Limits
Keep price, identity, and test boundaries visible.
