8. t Works continued Emissivity Emissivity is a term used to describe the energy emitting characteristics of materials Most 90 of typical applications organic materials and painted or oxidized surfaces have an emissivity of 0 95 preset in the unit Inaccurate readings will result from measuring shiny or polished metal surfaces To compensate cover the surface to be measured with black tape or flat black paint Allow time for the tape to reach the same temperature as the material underneath it Measure the temperature of the tape or painted surface Refer to table on page 8 Good Measuring Practices Holding the meter by its handle point the IR sensor toward the object whose temperature is to be mea sured The meter automatically compensates for temperature deviations from ambient temperature Keep in mind that it will take up to 30 minutes for the IR sensor to stabilize if going from ambient tem peratures to a much higher or lower temperature measurement Reminders e The unit is not recommended for measuring shiny or polished metal surfaces stainless steel aluminum etc See Emissivity above e The unit cannot measure through transparent surfaces such as glass It will measure the surface temperature of the glass instead e Steam dust smoke etc can prevent accurate measurement by obstructing the unit s optics Emissivity Val Substance an Substance pet
