I’m a big fan of Android smartphones with built-in thermal cameras, such as the Ulefone Power Armor 18T.

I also understand that some people don’t want to have to change their smartphone to be able to use this useful superpower.

If your Android smartphone is a rugged one, you may have trouble mounting the camera and need to get a USB-C extender.

One feature of the P2 Pro app that I really like is that along with the crosshair in the middle of the photo, there are two other crosshairs that record the highest and lowest temperatures in the photo.

Mounting a macro lens to the front of your camera allows you to get closer to what you’re looking at, giving you better resolving power to really focus.

This thermal camera is awesome, especially considering the price.

Not sure what you can do with one? Here are a few things you can do with a thermal camera:

  • Look for overheating electrical components (faulty components tend to run hotter).
  • Diagnose all types of HVAC problems, from heat-leaking windows to radiators that don’t heat properly to air conditioners that don’t cool.
  • Dangerous overheating condition detected rechargeable battery.
  • Find the radiator hose under the floor.
  • Find the overheated power cord.
  • Find cooling system problems on desktop and laptop computers.
  • Brake lock in place on car.

My advice when learning how to use a thermal camera is to use it to look at things when they’re not faulty — radiators, car brakes, electrical appliances, whatever — and that way you’ll know what things look like, so you can tell when things aren’t working properly.

Also: Every gadget enthusiast knows: There’s always a better tool.

I find thermal cameras so useful that I use them without thinking. Recently, I wanted to know if an electrical device was getting power. Instead of reaching for a multimeter, I used the thermal camera to see if anything was getting hot inside. When I saw the components getting hot, that eliminated a whole bunch of possible problems.

I’ve tested a number of thermal cameras — both standalone cameras and smartphone-attached cameras — and InfiRay P2 Pro is the best. It’s small, the macro lens makes it incredibly versatile, fast and accurate, and doesn’t need to be charged separately.

This is a great addition to any repair kit and if you’re an Amazon Prime member you can get it for $80 off its list price. iPhone version, while Android The version is currently discounted to $219.
