Calculating the Proper Emissivity Setting
Calculating the Proper Emissivity Setting ThermoWorks provides an Emissivity Table with the emissivity rating of many common materials listed. For measurements of many materials, inputting the right emissivity value is as easy as checking the chart. Chart values, however, are just estimates. The actual emissivity of a surface you're trying to measure will vary slightly depending upon its color, thickness and even its temperature. Verifying the precise accuracy of an infrared measurement can take a little more planning. This is particularly true when your infrared thermometer is set to lower... Read Now
Still Using Paper Temperature Logs?
Still Using Paper Temperature Logs? Paper temperature logs have been used for decades to track HACCP temps. In today’s age of connectivity and technology, restaurant owners who embrace new HACCP innovations are realizing significant cost savings, improvements in data accuracy, and faster more immediate corrective actions to protect their brands. So...what’s stopping your organization from moving to a paperless HACCP solution? Below we outline a couple of the latest innovations that are making the transformation to a paperless HACCP checklist painless and efficient. Chose the one that’s right for your... Read Now

Three Ways to Prepare for a Health Inspection
Three Ways to Prepare for a Health Inspection Whether you're in food processing, industrial manufacturing or at the operations level of restaurant management, health inspections happen. They usually occur two or three times a year - depending on the industry, and in many cases, can make or break the future of your business. Though it may be tempting to put off certain repairs or overlook a few minor health violations in the hopes that inspectors will not visit today, the better practice is to treat every day as the day...

Emissivity
Emissivity Not all surfaces are created equal. Depending on what you’re pointing your infrared gun at you’re likely to get variations in emitted infrared energy. This variation is called emissivity. What is Emissivity? Emissivity is a measure of a material’s ability to emit infrared energy. It is measured on a scale from just about 0.00 to just below 1.00. Generally, the closer a material’s emissivity rating is to 1.00, the more that material tends to absorb reflected or ambient infrared energy and emit only its own infrared radiation. Most organic...

The Temperature Danger Zone: What It Is and How to Avoid It
The Temperature Danger Zone: What It Is and How to Avoid It What is the Temperature Danger Zone The USDA calls the range between 40°F and 140°F (4°C and 60°C) the “Temperature Danger Zone” (TDZ) because it is the range in which harmful bacteria multiply quickly. What do we mean by “multiply quickly?” We mean doubling in as little as every 20 minutes. If that doesn’t sound super fast to you, consider this: If you have just 150 salmonella bacteria floating on a soup, in 20 minutes there could be... Read Now
