Better Accuracy: The Lasergrip’s 12:1 distance-to-spot ratio enables you to accurately measure targets from a comfortable distance. For best results, position the thermometer approximately 14.17 inches / 36 centimeters away from the target
Adjustable Emissivity: The upgraded Lasergrip lets you quickly change the emissivity from 0.1–1.0 by holding the Up and Down buttons. Whether you’re working on your car or testing the temperature of your grill, the Lasergrip can help you get the job done
Wide Range: Choose your preferred unit and measure temperatures anywhere within the upgraded range of -58°–842°F / -50°–450°C. Then watch as your result appears on the bright LCD display in less than half a second
Versatile Design: Infrared technology makes it easy to safely measure the surface temperatures of both scorching hot and freezing cold objects, such as ovens, AC units, grills, car engines, and refrigerators
Added Features: The new Lasergrip features a Maximum Temperature Mode as well as a backlit LCD display. Additionally, the auto-off function extends battery life, while the low battery indicator lets you know when it’s time for a new pair
2 x AAA Batteries Included: The Lasergrip has been upgraded to run on 2 pre-installed AAA batteries, which are more convenient to replace than 9V batteries
Do Not Use on Humans: The Lasergrip is intended for use on inanimate objects only. Measuring the temperature of a human or animal is unsafe
