The Fluke Calibration brand has grown over the years to encompass a broad range of products and services in electrical, rf, temperature, pressure, and flow calibration, plus calibration software. This infographic tells the story of how our brand has progressed over the years, and what we stand for. You might be surprised to see what we have in common with our colleagues in the Fluke Corporation “industrial” business, and how we’re different.

Many Fluke Calibration pressure measuring instruments require periodic zeroing of the reference pressure transducer to correct for drift that occurs naturally over time. For the transducers that are intrinsically absolute, the zeroing process is often performed by comparison to local barometric pressure. This is a relatively simple task for laboratories that have access to a precision in-house barometer. With the exception of a few low pressure ranges, zero by comparison to an in...

The thirtieth anniversary of the passing of Fluke founder John Fluke Sr. occurred earlier this year. To help celebrate his memory and share the vision that our company is based on, our colleagues in Human Resources made a short video. The video includes reminiscences from Fluke and Fluke Calibration associates (including yours truly) who remember what it was like to work at Fluke ”back in the day.”
Some of you may be in the calibration and metrology business long enough that you, too,...

In December 1968, astronauts William Anders, Frank Borman, and James Lovell became the first people to travel from Earth to another body in space. On the forty-fifth anniversary of that first voyage around the moon, NASA has released a new visualization combining new lunar reconnaissance data with Apollo 8 images and crew conversations to show how marvelous engineering, human spirit and a bit of luck combined to move the world with one of the iconic images of the 20th century.

(The live versions of the following webinars have past. However, they have been recorded and you can view them at our on-demand webinar page.)
Each month, Fluke Calibration hosts free, live web seminars including interactive Q&A sessions, on topics that include principles and practical tips about electrical, temperature, RF, pressure and flow calibration. The first seminars of 2014 have been announced. They include nine different seminars (including two in Spanish) on a wide variety of...

I have seen some interesting discussions in cyberspace about the recent shutdown of the U.S. Government. The measurement services of the National Institutes of Standards and Technologies (NIST) are on the “not critical” list of services, as is most of NIST itself. Many of these dedicated public servants are personal friends of mine, and I am saddened that they are prevented from doing what they enjoy the most, providing some of the world’s best calibrations. I personally hope that they...

A flowmeter measures the rate that fluid or gas moves through it. Test and measurement professionals use them in a wide variety of applications where accurate flow measurements are critical, including (but not limited to) HVAC, energy and utilities, water management, aerospace, agriculture and the pharmaceutical industry. In applications like these, it’s important to calibrate the flowmeters that make the measurements. Regular calibrations assure you that the flowmeter’s...

If you measure or calibrate pressure in the real world, you are at risk for contamination. And contamination can cause problems that you don’t even want to think about. A manufacturer in the aerospace industry found that out when they used their air system to calibrate a gauge that had water in it, then used it to calibrate another device that was supposed to be “dry and air pure.” That device was used on a water-free system under test and, you guessed it, water got into the system where...

I write this towards the end of the CALCON Conference at the Utah State University Campus in Logan, Utah. The conference is here because the Space Dynamics Laboratory is part of Utah State. CALCON is the "Conference on Characterization and Radiometric Calibration for Remote Sensing".
What is the difference between the radiometric calibration they speak of and the radiometric calibration I speak of when referring to radiation thermometry? In some aspects, I can answer this by saying...

Metrology is a very satisfying occupation but there will be roadblocks along the way. For some of us curve fitting is easy so long as we have a standard software package that solves our problem. But what do you do in a situation where your usual software program doesn’t work because you’re dealing with a non-linear equation? Such situations are not that exotic. For example, infrared thermometers are everywhere and typically impractical to adjust. If you want to provide a correction...
