Calibration Equipment & Standards and Calibration Software

Dry-block calibrators are stable temperature sources for calibrating sensors such as dial thermometers, resistance temperature detectors (RTDs) and thermocouples.These sensors are used for process manufacturing in many industries.They need to be checked or calibrated periodically. Watch the How to Calibrate a Digital Thermometer with a Dry Block video for an example.
Since dry blocks are portable, fast, and clean (do not use fluids), they are popular for on-site sensor...

If you’re in the market for an isothermal bath (temperature calibration bath), you may have already noticed that many suppliers provide technical specifications that are confusing or incomplete. You might only be able to find a performance spec for a single temperature point, not for the bath’s whole temperature range. Or they don’t say which bath fluid was used in testing.
An isothermal calibration bath is a significant investment so you need to get enough information – and the right...

A temperature probe is typically ordered with a termination that matches the calibration equipment it will be used with. For example, a 5615 Secondary Standard PRT used with a 914X Field Metrology Well would be ordered with a type A termination (INFO-CON DIN 6-pin).
If you want to use this 5615 probe with a different readout like a 1524 Reference Thermometer that does not accept a type A termination, what do you do? Check out our Probe-to-Readout Adapter Guide » to see which adapter is needed....

If one of your resolutions for the New Year is to learn something new, you will find many opportunities at Fluke Calibration to do just that. Some offerings are completely free, while other are more in-depth and carry a price tag.
Here is an overview of opportunities for learning at Fluke Calibration:
Fluke Calibration web seminars
This free web seminar program offers a robust schedule of courses where you will learn principles and practical tips about electrical, flow, pressure, RF and...

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...

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.

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,...
