Emissivity and Its Effect on Infrared Thermometer Readings

What is Emissivity?

According to the Merriam Webster dictionary, emissivity is

: the relative power of a surface to emit heat by radiation

: the ratio of the radiant energy emitted by a surface to that emitted by a black body at the same temperature

So, you could think of it this way: every material or object emits radiant heat or infrared radiation at its own specific rate. The specific rate at which it emits thermal energy depends on the type of material it is made of, its surface properties, and the temperature of the object itself.

Because an infrared thermometer is measuring the infrared emissions of the object to determine temperature, […]

NIST Certification of IR Thermometers

We offer an optional NIST certificate for our infrared thermometers. Read this article to learn more about NIST and NIST certificates, NIST traceability, and to decide whether a NIST certified unit is right for your needs.

NIST – The National Institute of Standards and Technology

Let’s start by explaining what NIST means. NIST is the National Institute of Standards and Technology, a physical science laboratory that is part of the U.S. Department of Commerce. It was founded in 1901 and is one of the nation’s oldest physical science laboratories. Its main purpose and mission is to develop and maintain measurement standards. As part of that mission, NIST provides certified standard reference materials (SRMs) […]

Keeping Food Safe with an IR Thermometer

Infrared Thermometers can Improve Accuracy and Efficiency in Food Safety Quality Control Processes

The CDC reports over 3,000 deaths and over 47 million cases of foodborne illness every year in the United States. While these numbers may seem staggering, there has actually been a great deal of improvement in food safety controls in recent years, including the 2011 passage of the Food Safety Modernization Act. The first time it has been updated since 1932!

New systems and solutions are being introduced throughout the food industry as new technologies improve monitoring and processes for refrigeration, food handling, transportation and all aspects of the food production and delivery chain. These new systems help […]

The Ultimate Emissivity Table

In one of our past articles, we have introduced the concept of emissivity and how a material’s emissivity affects the accuracy of our temperature gun readings. You may have experienced discrepancies when reading temperatures of rare or shiny materials. In our previous emissivity article, you discovered that different materials may require different emissivity settings in order for the temperature gun to give accurate readings. Changing the infrared gun’s emissivity setting should be done with the help of an emissivity table. […]

Homemade Soap Making Made Easy – The Essentials

How to Make Homemade Soap? That’s got to be complicated! I’ve heard it’s a trial and error thing…

What if I told you there are only a few things you need to make sure you get right in order to create your first homemade soap? […]

Laser Tape Measuring Like a Boss: Getting the Most out of Your Laser Distance Meter 📏

Oh boy, I love innovation… Especially when it transforms practical tools we already use and suprises us with dramatic improvements.

One tool that demonstrates this beautifully is the ever-present and reliable tape measure.

I’m pretty sure just about everyone has had an opportunity to put a tape measure to good use. There’s nothing to it, right? You just stretch it, place the start of the tape on one end and look at the measurement on the other. Easy peasy. Until it isn’t, so much… […]

10 Bug Out Bag Essentials 🎒 for the Zombie Apocalypse🧟

Okay, so maybe there won’t be a zombie apocalypse… 🤥 But you should still be prepared for the unexpected.

Depending on your location on the planet there are all kinds of unexpected and unpleasant possibilities these days, and sadly, they seem to be increasing. Whether it’s a wildfire, tsunami, tornado, an earthquake, volcanic eruption, a hurricane, or worse, any catastrophe calls for preparedness you can’t make up later – so it’s better to plan ahead. 😱 […]

🍕 Perfect Pizza Made Easy with a Laser Temperature Gun

Perhaps there is no better-loved food in all the world than a piping hot, crispy, crunchy gooey cheesy perfect pizza.

Whether your favorite is Hawaiian with Canadian bacon and pineapple, a Gorgonzola extravaganza, Vegan ‘alt-cheese’ and fresh tomatoes, peppers and ripe olives, a white sauce specialty with chicken, or a spicy pepperoni –  just thinking about it makes your mouth water. […]

Drone Safety: Here’s a Preflight Checklist Before Flying A Drone

Drones are becoming more accessible these days. Taking one out to fly a few times may make you feel like a professional drone pilot. They are so easy to operate, you’ll feel like a master in no time. But, don’t be fooled by these toy-like flying machines. They can pose serious risks – especially if they stop working mid-flight and crash into people. Drone safety should be considered even before flying that drone. […]
