Most (90% of typical applications) organic materials andpainted or oxidized surfaces have an emissivity of 0.95.Inaccurate readings will result from measuring shiny or polished metalsurfaces. To compensate, cover the surface to be measured with maskingtape or flat black paint. Allow time for the tape to reach the sametemperature as the material underneath it. Measure the temperature of thetape or painted surface.Measured Surfaces EmissivityMetalAluminum: Oxidization 0.2-0.4A3003 Alloy: Oxidization, Rough 0.3, 0.1-0.3Brass: Burnishing, Oxidization 0.3, 0.5Copper: Oxidization,Electric Terminal Board0.4-0.8, 0.6Hastelloy: Alloy 0.3-0.8Inconel: Oxidization,Sand-Blasting, Electro Burnishing 0.7-0.95, 0.3-0.6, 0.15Iron: Oxidization, Rusting 0.5-0.9, 0.5-0.7Iron (Casting): Oxidization,Non-Oxidization, Casting 0.6-0.95, 0.2, 0.2-0.3Iron (Forging): Passivation 0.9Lead: Rough, Oxidization 0.4, 0.2-0.6Molybdenum: Oxidization 0.2-0.6Nickel: Oxidization 0.2-0.5Platinum: Black 0.9continued...1.888.610.7664info@REED-Direct.com REED-Direct.com
