Seek Thermal Nano 300 Smartphone Thermal Camera (Android, USB-C) (Nano 300 (CQ-ADAX))

A smartphone thermal imaging camera for Android phones with a USB-C port, with a 320 x 240 sensor and a wide 56-degree field of view, powered by the phone.

Why people pick it

  • The widest field of view in the Nano line (56° x 42° per the spec sheet), which covers whole rooms and large surfaces in one view
  • 320 x 240 resolution with SV1 image optimization, the sharpest image Seek offers in a smartphone camera
  • Powered by the phone over USB-C, so there is nothing to charge and it is always ready
  • Spot plus min/max temperature readings and 7 color palettes in a free app

Know before you buy

  • High-resolution smartphone thermal cameras cost several times the Nano 200's price; the 300 is the premium model
  • Android USB-C only for this part number; iPhone buyers need the CW-ABAX (USB-C) or LW-ABAX (Lightning) version
  • Accuracy is the greater of ±9°F (±5°C) or 5%, so it locates problems rather than certifying exact temperatures
  • Fixed-focus optics; close-up work needs the separate macro lens accessory
