Ambient Temperature Effects in Infrared Thermometry1
- Ray D. Jackson and
- Sherwood B. Idso2
The output signals of two different infrared thermometers deviated drastically when internal console temperatures rose above 48 and 58 C. Internal temperatures greater than 48 C were observed in both instruments on all clear days investigated, rendering one instrument useless during the warmer parts of these days. In addition, one of the instruments also had a temperature-dependent calibration curve, which introduced severe uncertainties into its accuracy.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
