Not sure if this is part of the topic, but I constantly get different readings from boiler and stillhead, and sometimes overheating of flask walls or
bath can cause misreadings to thermoprobe even when everything is in check.
Only one mystery has happened, when stillhead reported higher temps than the boiler. Only explanation might be that the overheated boiler walls heated
the vapor even more and caused it to be actually hotter at the head than in the boiler. |
