The Klein Tools IR5 Infrared Thermometer gives you a fast, no-contact read on surface temperature, which matters when the surface in question is a live circuit breaker, an overheating motor, or a duct run you don't want to touch. Point it, pull the trigger, and get a digital readout without ever making contact with the surface you're checking.That non-contact design is the whole point: you can check temperatures on energized equipment or hard-to-reach spots safely and quickly, which makes this a practical add for electricians, HVAC techs, and maintenance crews doing routine diagnostics. It runs on a single 9-volt battery, which is included, so it's ready to use right out of the box. Built by Klein Tools and backed by a 2-year warranty, it's meant to hold up on the job, not just in the toolbox.
