The main difference is the slightly reduced temperature range - -58F (-50C) to 716F (380C). . IR thermometers rely on knowing how reflective your surface is (water, oil, cast iron, SS, etc). The distance to spot (D:S) ratio refers to the measurable surface area the infrared laser thermometer will read compared to the distance from which it takes that reading. Emissivity is a measure of a material's ability to emit infrared energy. 4.4 out of 5 stars 273. Objects with adjustable emissivity settings give emissivity values far from the exact temperature. . These can range from simple "high, medium and low" settings to fully adjustable settings. A non-adjustable thermometer may be used to measure the temperature of a reflective surface by applying a non-reflective paint or tape, with some loss of . Call us at 1-888-826-6342. The reflected temperature is extremely different than the surface temperature; This limitation applies to all thermal imaging systems. $16.99. Reflective Surface . The thermometer's optics sense emitted, reflected, and transmitted energy. To do that we correct for emissivity (E). Download : Download high-res image (107KB) Download : Download full-size image; Fig. [] The ennoLogic performed perfectly in all of the tests . Infrared thermometers utilize the concept of infrared radiation to determine the surface temperature of objects without any physical contact. Reflection (R) equals 1 minus E. When analyzed in a common TSR instrument, a dark-colored surface absorbs 90% of the heat energy and reflects 10%, while a light-colored surface absorbs 30% heat energy and reflects 70%. text.skipToContent text.skipToNavigation. Emissivity is defined by a ratio of infrared energy emitted by an object, compared to that emitted by an ideal . If an . Infrared thermometers are more accurate when used on materials with a high emissivity rating and fixed emissivity rating because those materials emit more thermal radiation. The surface temperature and interior temperature of the PS box were recorded by infrared temperature measurement and thermometer, respectively. Most of them allow you to adjust this value, but it requires you to know what to adjust it to (they usually have a guide). If I lower the emissivity coefficient to 0.07 Opaque (non-transparent) surfaces produce a combination of emitted and reflected radiation. For some materials emissivity is less than 1 and variable due to changes in material, surface oxidation, surface roughness, microstructure or coating. .
