Two-in-one thermometer for industrial use

The Fluke 566 combines infrared and contact temperature measurement in a single handheld tool. It is designed for technicians working in electrical, mechanical, and industrial environments who need to inspect equipment quickly. The rugged, ergonomic construction withstands tough daily conditions on site.

Distance-to-spot ratio limits target size

A fixed 30:1 ratio means the measurement spot grows larger as distance increases, so small components require the user to move closer. Temperature range spans -40 to 650 degrees-C with one percent accuracy, which constrains use to applications inside that window. Emissivity adjustment compensates for shiny surfaces, but only within the materials table or manual numerical entry provided.

Menu-driven setup with soft-key navigation

A three-button on-screen interface in six languages guides users through emissivity settings, data logging, and alarm configuration without a manual. The dot matrix display shows prompts clearly, reducing the chance of selecting the wrong parameter. Contact measurements require the optional probe to be seated firmly; loose contact is the most common cause of reading errors.

Questions about this item

Which version of the Fluke 566 should I choose for both infrared and contact temperature measurement?

The Fluke 566 is a single model that combines infrared and contact thermometry in one tool, so there are no separate versions to select.

What does the 650 degrees-C upper limit mean when I am measuring equipment in the workshop?

You can measure surfaces up to 650 degrees-C (1202 degrees-F) with one percent accuracy, covering most industrial, electrical and mechanical inspection tasks.

How does the 30:1 distance-to-spot ratio affect the size of the area I can measure from a distance?

At 30:1, the measurement spot is one thirtieth of the distance to the target, letting you measure smaller objects or stand further away while keeping accuracy.
