Accurate enough for lab use, and rugged and portable enough to take anywhere
• Best-performing industrial heat sources (accuracy, stability, uniformity) in the world
• Immersion depth to 203 mm (8 in)
• Optional ITS-90 reference input reads PRTs to ±0.006 °C
• Temperature range from –45 °C to 700 °C

Every once in a while, a new product comes around that changes the rules. It happened when we introduced handheld dry-wells. It happened when we introduced Micro-Baths. Now we’ve combined bath-level performance with dry-well functionality and legitimate reference thermometry to create Metrology Wells.

With groundbreaking new proprietary electronics from Fluke Calibration's (patents pending), Metrology Wells let you bring lab-quality performance into whatever field environment you might work in. New analog and digital control techniques provide stability as good as ±0.005 °C. And with dual-zone control, axial (or “vertical") uniformity is as good as ±0.02 °C over a 60 mm (2.36 in) zone. (That’s 60 mm!) Such performance doesn’t exist anywhere else outside of fluid baths.

In short, there are six critical components of performance in an industrial heat source (which the European metrology community explains, for example, in the document EA-10/13): calibrated display accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, impact from loading, and hysteresis. We added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells.

(By the way, Metrology Wells are the only products on the market supported by published specifications addressing every performance category in the EA-10/13. Our specs aren’t just hopes or guidelines. They apply to every Metrology Well we sell.)

Two-in-one contact and IR thermometer with innovative dot matrix display.

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



With a rugged, easy-to-use ergonomic design, the Fluke 568 and 566 two-in-one contact and non-contact thermometers can handle tough industrial, electrical, and mechanical environments. These tools outperform any other IR thermometer (or pyrometer), helping you work more efficiently in a wider range of applications.

Portable multi-function calibrator simplifies calibration work

Whether you're calibrating instruments, troubleshooting a problem, or running routine maintenance, the Fluke 754 with HART® communication can help you get the job done faster. It does many different tasks quickly and it's the only process calibrator you need to carry.
