Infrared and Contact Thermometers: Fluke 568 and 566

 Laser Temperature Gun: Fluke 568 and 566
Two-in-one IR and contact thermometers with an innovative dot matrix display.

With a simple, 3-button on-screen menu interface (in 6 languages) the Fluke 568 and 566 digital laser thermometers make even complex measurements easy. Quickly navigate advanced features to adjust emissivity, start data logging, or turn on and off alarms - with just a few pushes of a button.

With a rugged, easy-to-use, ergonomic design, the Fluke 568 and 566 two-in-one contact and non contact thermometers can stand up to tough industrial, electrical, and mechanical environments. These tools go beyond other IR thermometers (or pyrometers), helping you work more efficiently in more applications.

Added functionality available only on the 568:

  • Easily trend and analyze data with included FlukeView® Forms software
  • Quickly download stored data with USB connection
  • See your data right away without leaving the site, using the USB and your laptop
  • Extend your battery life by powering the digital thermometer from your laptop via the USB

Features and benefits of the 568 and 566:

  • Measure -40 °C to 800 °C /-40 °F to 1472 °F (568) or -40 °C to 650 °C/-40 °F to 1202 °F (566)
  • Easily access advanced features with the soft-key buttons and dot-matrix display
  • Measure smaller objects from further away, with a distance-to-spot ratio of 50:1 (568) or 30:1 (566)
