Emissivity Labels

An emissivity sticker improves the accuracy of infrared thermometers and thermal imaging cameras by providing a known emissivity value of 0.95. Different materials emit thermal radiation with varying efficiency, affecting temperature readings. By applying the sticker to a surface, the infrared sensor reads the temperature of the sticker’s consistent emissivity, eliminating measurement deviations from reflective or low-emissivity surfaces, and ensuring accurate and reliable measurements.

How do I determine the emissivity of an unknown object, using an emissivity sticker?

For temperatures up to 380 C, apply a plastic emissivity sticker, set the emissivity to 0.95, and measure the temperature of the sticker. Then, measure the adjacent area and adjust the emissivity accordingly. Ensure the object temperature differs from the ambient temperature for accurate results.

Can I use the emissivity sticker for other wavelengths?

The emissivity stickers are optimized for wavelengths from 8-14 µm. For short-wavelength sensors emissivity has less effect on the measurement reading.
