Ever since I automated my system using DS1820 I have always thought that the reading must have been slightly off, I figured it was just placement in the mash or elsewhere, but I just never seemed right.
Finally, yesterday during a mash, I figued I would follow the probe around with a glass thermometer, which I had not calibrated. Looked to me like my DS1820 was reading at least 0.5C lower than it should have been and as high as 1.5C lower than the glass one.
I figure its really is reading wrong, I have often had problems getting my final gravity spot on and I guessed it may have been my attenuation, maybe not getting enough oxygen???? BUT, now I think that it might be generating too many unfermentables!!!!!! <_<
Anyone else out there using the older DS1820 digital thermometers??? Have you upgraded to the DS18S20 and seen a better reading???
According to this document, the DS18S20 fixes the problems associated with the internal algorithm to determine temperature.
