Buying decision
Decision
Higher native pixel count in a tiny phone attachment for broad surface scanning.
Choose Seek Thermal Nano 300 for broad surface scanning with a tiny phone attachment and a higher native pixel count; select the exact connector and operating-system variant. Skip it if you need a rugged standalone tool or assume every USB-C variant works across iOS and Android. No guide-author hands-on testing or substantive independent professional Nano 300 verdict was established.
Specs
Native detail and workflow fit matter more than a headline pixel number.
Seek confirms 320 × 240 is the Nano 300 actual sensor resolution; Nano 200 is a separate 200 × 150 model. The FAQ limits Nano video to five minutes, says tablets are not intended/tested, and describes accuracy as ±5 °C or 5%. Nano is not ruggedized; the FAQ distinguishes iOS USB-C, iOS Lightning and Android USB-C variants.
| Dimension | Value | Evidence note |
|---|---|---|
| Native thermal resolution | 320 × 240 | Manufacturer specification or rating; not independently measured. |
| Form factor | Phone attachment | Manufacturer specification or rating; not independently measured. |
| Phone connection | Separate iOS USB-C, Lightning and Android USB-C variants | Manufacturer specification or rating; not independently measured. |
| Power / rated runtime | Phone powered | Manufacturer specification or rating; not independently measured. |
| Focus | Unknown | Manufacturer specification or rating; not independently measured. |
| Best fit | Native thermal pixel count | Editorial inference from sourced features; not a measured ranking. |
| Thermal frame rate | 25 Hz | Manufacturer specification or rating; not independently measured. |
| Thermal field of view | 57° × 42° | Manufacturer specification or rating; not independently measured. |
| Measurement range | −20 to 330 °C | Manufacturer specification or rating; not independently measured. |
Workflow
Test the exact connection and inspection workflow.
Test the exact phone, connector, adapter, and inspection workflow during the return window. Select the Nano 300 variant for the exact operating system and connector; the official HTML and FAQ support the listed specifications. No substantive independent professional Nano 300 test is available, so this guide offers no performance verdict. Higher pixel count does not establish superior temperature accuracy.
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
No professional Nano 300 verdict was established.
No substantive independent professional written Nano 300 test was established. The review announcement’s linked video was unavailable and contained no usable verdict; app reviews and a mixed-model owner thread provide bounded signals only. This absence is an evidence gap, not a positive or negative verdict.
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.
Select the Nano 300 variant for the exact operating system and connector; the official HTML and FAQ support the listed specifications.
