High emissivity tape
Web11 de mar. de 2024 · The equipment is calibrated using two standard samples, one with a high emissivity and the other with a low emissivity, which are placed on the heat sink. The accuracy of the measured values is ±0.02. The emissometer output is 2.4 millivolts nominal, with sample emittance of 0.90 and sample temperature of 25 °C. Most high-quality electrical tape has an emissivity of 0.95. One must be careful, especially with mid wavelength cameras (3-5 μm), that the tape is opaque. Some vinyl tapes are thin enough to have some infrared transmittance, and are therefore unacceptable for use as high-emissivity coatings.
