Overloaded breakers, failing motor bearings, hidden water intrusion, gaps in insulation — they all announce themselves in heat long before they fail visibly.
The Klein Tools TI250 puts that information on a large LCD instantly: point it at a panel, wall, or piece of equipment and unseen hot and cold spots appear in over 19,200 pixels of thermal resolution with your choice of three color palettes (Ironbow, Rainbow, Grayscale).

The TI250 automatically flags the highest and lowest temperature points in the frame and gives you crosshairs to pinpoint the exact temperature of any spot.
User-selectable high and low temperature alarms let you scan a row of breakers or terminations and get flagged the instant one crosses your threshold. Adjustable emissivity (0.10 to 0.99) keeps readings accurate across shiny metal, painted surfaces, and everything in between.

The whole unit runs on a rechargeable lithium-ion battery — no fishing for 9V batteries in the truck — and captured images transfer over USB for inspection reports and customer documentation.
Measurement range runs -4°F to 752°F (-20°C to 400°C), covering everything from refrigeration lines to overheating connections. Please note: Klein has produced two revisions of the TI250; verify the resolution and charging port of current stock if that detail is critical to your workflow.
