temperature calibration
Just completed my reflux still (offset) and distilled some water to do a test run. The vapor temperature in the column stabilized at 203.6F with reflux valve wide open. I have 30" of copper mesh in the column. I need to calibrate the thermometer. Can I use the vapor temperature as a reference for adjustment or will it be different than the actual temperature? The boiling point of water at my barometric pressure and altitude should be 209F.

I would just boil some water and cal to that .. I myself dont really try to get it dead on the biggest thing i use a thermometer for is the temp changes thats the most important. its better to have a good sensitive thermometer . that is more useful that one thats dead on and responds slow. after a few runs ya may not even pay alot of attention to it anyways ..

As nm said, don't worry so much about accuracy as temp readings will vary quite widely with different stills or placement position. It is much more important to be able to notice temp fluctuations ie rises or falls as you run your unit.
For this reason, stick it in some boiled water and adjust to that, it will be close enough, 1 or 2 degrees or even a bit more will mean nothing in the long run.
