Infrared Thermometer with Laser Sight and ThermoSounder





  The LTX12 is a contactless infrared thermometer with laser sight, and is also the first IR thermometer in the industry offering the additional benefit of a variable audio feedback tone (ThermoSounderTM) for quick and easy detection of both cold and hot spots on any surface being tested for temperature uniformity and/or temperature variations.

  Useful in all kind of applications such as automotive, industrial, marine, agricultural, aviation, HVAC, farming and general temperature measurement applications where performing quick measurements, measuring from a safe distance or in hard to reach places is required.

  The LTX12 offers a temperature measurement range of -20 DEG F to 1200 DEG F, a 10:1 optical ratio and it comes loaded with a laser pointer, IR sensor, large LCD, selectable scales (˚C/˚F), backlight, laser On/Off feature, user's manual and a convenient soft pouch for carrying and storing the unit.


  • The exclusive ThermoSounder™ feature, provides users with audio feedback allowing for quick and easy detection of both cold and hot spots, without the distraction of having to follow and interpret the digital readouts
  • State of the Art patented ergonomic design and styling for enhanced handling and use
  • Wide temperature range: -20° to 1200° F ( -30° to 650°C)
