InfiRay T3S 384x288 Thermal Measurement Tool

SKU CH-W88H-ZVA8B MPN T3S

A 384x288 thermal imager for Android Type-C phones that detects heat loss, electrical faults and water damage

  • Product typeThermal Imager
  • High-resolution 384x288 thermal sensor reveals fine temperature detail
  • 13 mm lens provides wide field of view for PCB and floor scans
  • 17 µm pixel pitch captures subtle heat differences on components
  • USB Type-C plug-and-play turns an Android phone into a thermal imager
  • 8-14 µm spectral band detects heat loss, leaks and electrical faults in total darkness

Compact Android thermal imager

The InfiRay T3S is a miniature thermal imaging camera that plugs directly into an Android smartphone through a Type-C port. It delivers a 384x288 infrared sensor with 17 µm pixels and a fixed 13 mm lens covering the 8 to 14 µm spectral band. The plug-and-play design turns a compatible handset into a portable inspection tool for electrical, building and outdoor use.

Upgrade from single-spot pyrometers

Users moving up from single-point temperature guns gain a full thermal frame that reveals patterns across PCB traces, floor heating loops or insulation gaps. The jump is worth it when a temperature map spots a fault that a single reading would miss, such as a developing hotspot on a circuit board or a hidden water leak behind a wall.

Simple plug-in with focus attention

Installation is limited to inserting the Type-C connector and launching the companion app; no batteries or separate power are required. The main practical issue is achieving sharp focus on the 13 mm lens for the intended working distance, as the fixed optic cannot be adjusted after mounting.

Questions about this item

Does the 13 mm lens and Type-C connector clear my phone case?

The 13 mm lens sits on a short Type-C plug that fits most slim cases; thick or rugged cases may block the connector or vignette the 384x288 sensor.

What is the correct order to launch the app and attach the T3S?

Install the InfiRay app first, grant camera permission, then plug the T3S into the Android Type-C port; reversing the order often leaves the 384x288 feed undetected.

How do I keep the 17 µm pixel sensor accurate over time?

Wipe the 13 mm germanium window with a lint-free cloth, avoid dropping the unit, and run the in-app flat-field calibration whenever the 384x288 image shows fixed-pattern noise.
