Fluke 566

The Fluke 566 two-in-one contact and non contact thermometer can stand up to tough industrial, electrical, and mechanical environments.

Features and benefits of the 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)

• Compatibility with all standard miniconnector Type-K thermocouples allow you to preserve your thermocouple investments

• Confidently measure a wide variety of surfaces, with the adjustable emissivity feature, including a built-in material table

• Capture multiple points of data (up to 99 with the 568, and 20 with the 566), for downloading and recalling later

• Easily adapt to lighting conditions with 2 levels of backlight

• Audible and visual alarms instantly alert you to measurements outside of your set limits

• Quickly identify problems with the MIN, MAX, AVG, and DIF functions

• Make contact thermometer measurements right away with the included Type-K thermocouple bead probe

• Confidently troubleshoot equipment with 1% measurement accuracy

• Versatile interface with 6 languages from which to choose
