Summary: In this podcast, we talk about concepts in metrology and measurement. We focus on calibration and measurement uncertainty.


 Amazon | File Type: audio/mpeg | Duration: 13:30

Testing and calibration are alive and well in our Amazon fueled retail world of today. Want to sell a product on Amazon, find out about what they are going to require before you do.

 Why am I Cold? | File Type: audio/mpeg | Duration: 13:54

With the holiday season upon us, it seemed like the perfect time of year to answer the question, why am I cold? You have the thermostat set at 68 or 70ºF and yet you are freezing. Here's a hint, it has to do with the energy in the air, which has more to do with it than just temperature.

 Let's Talk Turkey | File Type: audio/mpeg | Duration: 13:11

Turkey, in a calibration PodCast? Yep, it is that time of year and time to share a little measurement science about the big ol' bird we all love to feast on.

 PID Tuning | File Type: audio/mpeg | Duration: 15:25

Had a fun little PID tuning event this week, so I figured I'd share my experience with everyone.

 IR & Emissivity | File Type: audio/mpeg | Duration: 12:37

IR temperature guns are being used everywhere today, and for a good reason. They are inexpensive and eliminate errors associated with measuring surfaces. Unfortunately, they also introduce errors that need to be understood by the end user to ensure quality measurements.

 Constants | File Type: audio/mpeg | Duration: 15:01

The field of metrology, like all scientific fields, is loaded with constants. These are important to be aware of, and it is also to be aware that constants aren't always, so, well, constant.

 Calibration Jobs | File Type: audio/mpeg | Duration: 10:05

Calibration jobs are out there everywhere. The problem is that we don't have near enough folks to fill the positions that are available. If you're interested in all of the things we talk about and your not a technician, this just might be the podcast for you!!

 Deceptive Statistics | File Type: audio/mpeg | Duration: 10:34

Math is pure and beautiful. Statistics is a branch of math that can be a little fuzzy but are completely necessary to understand measurement concepts. The study of statistics is a core competency of measurement science, and nothing irks me then why the fine folks out there in journalism get a hold of numbers and find ways to try to make sure you don't sleep at night.

 The Impact of 17025:2017 on Customers | File Type: audio/mpeg | Duration: 15:44

With the transition to the ISO calibration standard 17025 moving to its newest revision, how will customers of calibration services be impacted? 

 On the Cheap | File Type: audio/mpeg | Duration: 16:14

Sometimes we don't have the budget to buy the newest calibration toy for a given situation and we need to improvise. I want you to get creative when the need arises, and today I give you a couple of suggestions about how to do exactly that. 

 Meter or Miter | File Type: audio/mpeg | Duration: 03:54

I know this one might sound crazy, but why do we pronounce the "meter" in the word thermometer differently than we do in the word multimeter? Well, it's all about the "O."

 Temperature Signals | File Type: audio/mpeg | Duration: 23:41

Recently, I purchased some RTDs for a project only to receive them in bags marked thermocouples. So many people use the term thermocouple when they mean temperature probe, and this can lead to a lot of confusion for us control type folks.

 Calibration in the Workplace | File Type: audio/mpeg | Duration: 13:39

Everywhere I turn I see more and more calibration happening. It's a function of our modern world of outsourcing and suppliers and it is not going away. In fact, it just seems to be growing at an exponential pace. How did it evolve this way, and why?

 Testing is Everywhere | File Type: audio/mpeg | Duration: 07:29

On a recent trip to Alexandria, VA is really managed to have my eyes opened to the amazing amount of testing that happens out there in ISO 17025 world. I've always thought of the standard as one that revolves around calibration, but there is so much more.

 Miles to E | File Type: audio/mpeg | Duration: 05:53

We all know that miles to "E" thingy on our dashboard lies to us, but by how much. Today, I share my experience with an experiment I did a while back on this topic.
