Managed to get better data today with a styrofoam ice chest and no stirrer. It isn't as easy as it sounds to get water to stabilize within 0.01C for a minute to record temps...
Here is the obligatory graph (I regraphed yesterday's results as well because numbers are VERY close)
And for Les:
Code:
Digitec MAX6655 Std Dev
40.62 42.65 0.108
31.58 32.88 0.097
24.79 25.79 0.06
13.34 14.42 0.09
04.55 05.56 0.09
MUCH better this time. I have a suspicion calibration will continue to improve as I practice. That oven sounds like a good purchase though I have to say...
