The Fluke 566 Infrared and Contact Thermometer features a simple, 3-button on-screen menu interface (in 6 languages). Users can easily and quickly navigate the advanced features with just a few buttons to adjust emissivity, start data logging, or turn on and off alarms. The ergonomic yet rugged design improves comfort and makes it easier to use, while at the same time allows for longer life tough industrial, electrical and mechanical environments.
