Leaving thermometer in carboy
« on: January 15, 2010, 03:24:37 pm »
Is it a bad idea to leave a sanitized thermostat probe dangling down into my carboy while my beer ferments? I would like to just be able to turn it on and know what the fermentation temps are. I wonder if this will cause a seal problem with my blow off tube / airlock... Was wondering if anyone had thoughts on it.

I thought about doing it but have never done it.  I can't see how it would cause any problems as long as the probe was made for submersing in liquid.

Most probes that I know of have a weak spot for liquid at the juncture between the probe and wire.  Just a heads up.

Why not just use a Fermometer?  Cheap and accurate....

Those stick on thermometers are a lot less hassle and are accurate enough for brewing. I got 6 and they are all within 2 degrees f.

There are also those Thermowells that are built into a rubber stopper and have a long SS sleeve that goes down into the fermenting beverage and gets a much more accurate reading that way (glass is a hell of an insulator).
