AB  - This paper sums up the determining analysis of the measuring location of <i>T<sub>refl</sub></i> using a thermocouple during the thermography tests. Laboratory temperature distribution testing methods, analysis of value and location of <i>T<sub>refl</sub></i> measurement are explained in this paper. The heat source is two halogen lamps of 500 watts each fitted at a distance of 30–50 cm. Noises appearing during testing of thermography are corrected with measured <i>T<sub>refl</sub></i> value. The results of thermogram correction of corroded concrete surfaces using <i>T<sub>refl</sub></i> values are displayed in this paper too. The concrete surface temperature results of quantitative image processing method are compared to the experimental test results. The results showed good accuracy, which was seen from most errors <3% and the maximum error is <5%. The end of paper, explained of application <i>T<sub>refl</sub></i> value to the corroded reinforced concrete thermogram.
