The authors work out the method that surface condensation of wall is measured by using Multi-Spectral Scanner(MSS), and experiments concerned are conducted on aluminum boards. The results are summarized as follows : (1) It was clarified that the data of spectral radiance acquired by MSS decline in infrared regions, especially at 1500nm and 2000nm, as surface condensation goes on. (2) Progressing degree of surface condensation was expressed by radiant intensity ratios, such as 1600nm/1500nm and 2100nm/2000nm. (3) Correspondence between spectral radiance ratio of 1600nm/1500nm and weight of condensation liquid water was analysed.
