Emissivity
• Most organic materials and painted or oxidized
surfaces have an emissivity of 0.95.
• Inaccurate readings might occur while
measuring shiny or polished metal surfaces. To
compensate for this, cover the surface to be
measured with masking tape or flat black paint.
• Measure taped or painted surfaces when the
tape or painted surface reaches the same
temperature as the material underneath.
