Temperature of room, L, 15° C. ; 11., 17° C. 
From calibration of couple before experiments, 
1° C., between 0° C. and 100° C. = 4'24 scale divisions. 
1° C., between 100° C. and 200° C. = 4*25 scale divisions. 
From calibration of couple after experiments, 
1° C., between 0° C. and 200° C. = 4'25 scale divisions.
