Fig. 2(a and b) shows the result of different exposed wire lengths
for both sizes of thermocouple, 80 mmand 200 mm. The vertical axis
indicates the difference between the thermocouple measured
temperature and the peltier (PT100 measured) surface temperature
while the horizontal axis represents the peltier surface temperature.
The maximum temperature drop is equal to 2 C and 4 C for
80 mm and 200 mm respectively with an environment temperature
of 13 C and the peltier surface temperature of 35 C.
