		<description><![CDATA[Emissivity makes a temperature difference for infrared thermometers. In the YouTube video below, Frank Liebman, an engineer with Fluke Corporation&#8217;s Hart Scientific Division demonstrates the impact that surface emissivity has on temperature measurement and temperature calibration using a modified Fluke blackbody calibrator and Fluke Thermal Imager. We were surprised to see that no one commented [...]]]></description>

		<description><![CDATA[Electro Optical Industries (EOI) uses one of two high emissivity coatings on the surface of its blackbodies. The EOI mid-temperature coating is used on both cavity and flat plate blackbodies that have a maximum operating temperatures of up to 210 °C.

		<description><![CDATA[From the Electro-Optical Industries website: &#8220;Effective emissivity is the ratio of the total amount of energy exiting pharmacy websites a blackbody to that which is predicted by Planck’s law. This is the value most frequently referred to as &#8220;emissivity&#8221;. Effective emissivity of a cavity type blackbody will normally be much higher than the surface emissivity [...]]]></description>

		<description><![CDATA[It is not an oxymoron, nor a quote from Yogi Berra. Real Blackbodies do not exist, at least on Earth. Only approximations or simulations are real. We use them to calibrate IR Thermometers, Radiation Pyrometers and Thermal Imagers. Technically they should have a spectral emissivity very close to 1.0. How close, you might ask?
