the airpressure on April 28th 2011 was 1011 mbar, so the boilingpoint
must have been 99.9 degC. The difference in boilingtemperature can be
explained by the accuracy of the thermometer (+/- 0.4 degrC).
At these temperatures with boiling water I doubt the water temperature
was uniform. I have recently been calibrating some thermocouples and
thermometers at various temperatures. I have seen considerable
non-uniformity. There is no mixer inside the eCat. Barometric pressure
also varies during the day and from place to place. A 0.4°C difference
from the boiling point based on weather reports is not surprising.
I will upload some notes about my calibration.
