Calibration Equipment & Standards and Calibration Software
Aug 25, 2015
To calibrate an industrial temperature sensor like a PRT, RTD, thermistor, or thermocouple, you put the sensor into a stable industrial temperature readout like a dry-well, furnace, or calibration bath, and then compare the sensor’s output to the output of a reference standard probe connected to a thermometer readout. There are many different types of reference standard probes and thermometer readouts, and many ways to combine them, so knowing what to purchase can be a little confusing. We can...

Pressure controllers / calibrators, also referred to as pressure controllers, are pressure standards that combine digital reference pressure standards with hardware to automatically set and control pressure. Pressure controllers are typically bench-top systems, but can sometimes be fixed (rack), portable and/or transportable.
Here are six reasons why a pressure controller/calibrator might be just what you need to calibrate pressure:
1) Ease of use – Generating and measuring a pressure is as...

Thermocouples are broadly used in many industrial and scientific applications. But it can be a bit tricky to understand how they work and how to calibrate them.
We've developed a thermocouple application note series created by temperature calibration experts to help you learn what you need to know. The series covers how thermocouples work, choosing calibration equipment, calculating uncertainties, and how to calibrate thermocouples.
There are four application notes in the series:
Thermocouple...

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...

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...

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...

If you use Fluke Calibration electrical calibrators or software, chances are you and I have talked on the phone at least once.
I’ve been providing technical support for calibration products for the last 14 years; the last five as manager of a five-member team at Fluke Calibration. Together we field approximately 65 telephone calls each day, plus more than 2,300 emails per month (more than 8,000 emails in 2012). My team supports the Fluke Calibration electrical calibrators and standards,...

I’m a big fan of calibration baths. When I managed our temperature calibration laboratory, I relied on them. With a series of baths and a liquid nitrogen comparator, we were able to perform a large volume of accredited temperature calibrations with lower uncertainties from -197 °C to 500 °C than would have been possible in any other way. Sometimes we would get a probe that was large and bent, or very small, or had a large handle and it would slow us down, but it would not stop us, because the...
