A friend of mine was concerned about heat loss/gain in one room of his residence. The room was cold in the winter and hot in the summer. To help diagnose the problem he purchased a little device called the Seek thermal Compact that plugged into his smart phone to provide a thermal image of the room.
What Does It Do: The Seek thermal Compact is a thermal imaging camera that plugs into your smart phone or tablet to allow it to take thermal images or videos of anything including buildings and building systems.
System Requirements: iOS or Android smart phone or tablet
What does it cost: $249 – $499 (depending on model)
How Does it Work: Simply plug the camera into your smart device to capture a thermal image or video that will show energy loss/gain caused by air leaks, missing or damaged insulation, inefficient HVAC systems, electrical faults, and more. You can save, send, share, and store the thermal images or videos the same way you would any other image or video on your smart device. This compact, pocket-size, portable device measures only 1 x 1.75 x 1” and weighs less than 0.5 ounces. It runs on power from your smart device, does not require batteries or charging, and has low power consumption (up to 4 hours of battery operating time). There are three models of the Seek Compact: the Compact, the CompactXR and the CompactPro. The main differences are the size of the thermal sensor, field of view, frame rate and detection distance. For design professionals the Compact or CompactXR would probably be sufficient.
Conclusion: This looks like a useful device for quick, convenient on-demand thermal imaging with your smartphone or tablet.
