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, […]
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 […]
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. […]
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? […]
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. […]
No matter how you plan to use your Himalayan salt block, you will want to know what temperature it is when you are cooking, chilling or serving fresh foods with it. Use the ennoLogic eT650D infrared non-contact thermometer to get an instant, accurate and safe reading of the temperature of your salt block. The eT650D allows you to point and shoot from a safe distance. At the same time, it determines the precise temperature of your salt block. You can also check if that temperature is uniform throughout the block. […]
Aside from the great uses of the ennoLogic eT650D Infrared Thermometer in the kitchen, it is a powerful tool you can use to help you get the best out of other chores around the home. You can use it to check if conditions are right before you start with chores. You can check for acceptable surface temperature before you start with exterior painting or window washing. […]
One of the most exciting and useful applications of a dual laser temperature gun, such as the ennoLogic eT650D, is as an automotive infrared thermometer. Use the temperature gun to troubleshoot, diagnose and perform routine spot checking of car system performance for everything from brakes to radiators, HVAC system, and engine timing. […]
You’ll be surprised at how many different uses you can find for an infrared thermometer in the kitchen. You can use it while cooking, tracking heat of frying oil, making sure foods are not too cold and not too hot, and even keeping track of food safety.
But before we dive into all these practical uses, you have to understand the fundamentals of how infrared thermometers work. It is important to know that infrared thermometers always measure surface temperatures. This type of thermometer can provide accurate readings of the temperature of the oil in your sauté or stir-fry […]
