Johnson Temperature Probe as an immersion thermomiter
I have a digital Johnson control I use for my lagering fridge but I'd like to use it as an immersion thermometer as a way of more accurately controlling the beer temperature. Anyone know if that probe is waterproof and/or food grade safe on the housing and probe?
Are you asking about inserting the probe into your fermenting vessel in order to get an accurate reading of the wort temp? If so, you'll need a thermowell in a stopper which allows you to insert the probe into the beer without it actually getting wet.
I had the same problem, just forgot about that issue as it's been a while. I never found a thermowell that would fit the johnson probe, so instead I got a replacement probe and rewired. I'll see if I can dig up the replacement part.
