Temperature
243.1 $\pm$ 0.5 $K$
Time at T
0.0 $min$
Temperature max
443.0 $K$
Time at Tmax
600.0 $min$
Comments
Sample temperature error is mostly due to possible vertical temperature gradient in the sample. Temperature reading accuracy and stability is 0.1K - Small pressure applied during sample flattening with a spatula
Type
