Non-Contact Temperature Measurement

The new Raynger MX family of handheld, infrared thermometers takes non-contact temperature measurement technology into the future. Designed for ease-of-use, unmatched performance, and featuring new laser sighting technology, the MX is the professional’s tool of choice.


With Raytek graphing software, you can use your computer to organize, display, and print temperature and time data. The software also includes the ability to store up to 10,000 data points; continuous or manual single-point recording; programmable time intervals; temperature sales and limits; built-in material table of emissivity values; customizable log locations; and displays both contact and infrared temperatures.


  • Check for hot spots in electrical panels, circuit breakers, generators, and gearboxes
  • Monitor supply and return registers, air stratification, and duct leakage
  • Monitor temperatures of gasoline and diesel engine cylinders and railroad axles and bearings

Also Available:  The Raynger 3i

In addition to displaying real-time temperature, the Raynger 3i calculates maximum, minimum, difference and average temperature values, while the Recall feature allows you to recall the last temperature reading. The 3i also compensates for energy reflected by the background around your target so it doesn't affect your reading and the backlit display makes it easy to read the display in poor lighting conditions. A locking trigger allows unattended operation, while adjustable high and low alarms signal over- and under-range temperature conditions. And each 3i comes with a padded nylon carrying case, shoulder strap and tripod mount.

Other styles are available.  Please call for more information.
