Who the Fluke 568 Is For

The Fluke 568 suits technicians who routinely measure hot, moving or hard-to-reach surfaces and still need a contact probe when emissivity or surface condition makes IR alone unreliable. Typical buyers include:

• Industrial maintenance teams inspecting motors, bearings, steam lines and process equipment
• HVAC technicians checking supply/return registers, coils and duct surfaces from a safe distance
• Electrical and mechanical troubleshooters who want Min/Max/Avg/DIF plus date-stamped logging
• QA and facility teams documenting temperature trends without carrying a separate contact meter

If you only need quick IR spot checks outdoors or on low-risk jobs, a simpler gun like the Fluke 62 MAX may be enough. Choose the 568 when you want IR + K-type contact + adjustable emissivity + 99-point logging in one instrument.

How the Fluke 568 Compares

Against the pocket-friendly Fluke 62 MAX infrared thermometer, the 568 adds a much wider IR range, 50:1 optics, a contact probe input, emissivity control and onboard logging — so it is the better pick for plant and HVAC diagnostics, while the 62 MAX wins on size and everyday spot checks. If you are still deciding between probe and IR methods, read our guide to contact vs non-contact thermometers before you buy.

What Comes in the Box

• K-type thermocouple bead probe
• FlukeView Forms software and USB cable
• 2 AA batteries, hard carrying case, quick start guide and user manual

FAQ

Does the Fluke 568 measure with a contact probe as well as infrared?

Yes. Besides −40 to 800 °C infrared readings, it accepts standard mini-connector K-type thermocouples for direct contact measurements up to 1372 °C (probe dependent).

When should I choose the Fluke 568 over the Fluke 62 MAX?

Choose the 568 when you need contact capability, adjustable emissivity, 50:1 optics and logging. Choose the Fluke 62 MAX for compact, everyday IR spot checks.

Can I log and export temperature readings from the Fluke 568?

Yes. The meter stores up to 99 dated points and connects by USB with FlukeView Forms for documentation and reporting.
