7. Distance to Spot Ratio infrared energy it will emit at a particular The thermometer has an optical angle and spot temperature. And the meter’s emissivity is more size as shown below. close to the material’s emissivity, the more particular measurement result you can get. So, it is important to set a just emissivity according to the material. 1. Model A and model C have a fixed (non-adjustable) emissivity of 0.95.
