It's sometimes called a laser thermometer, because you use the built-in laser to target the surface, but actually it's an infrared thermometer that measures electromagnetic radiation coming from the surface. It's the safest way to measure temperatures in hazardous areas (like automobile engines or other machinery), hard-to-reach places and other areas where a non-contact digital thermometer makes the most sense. LCD backlit display reads to 1/10 of a degree in Fahrenheit or Celsius. 40-hour battery life.
