Does anyone have any good suggestions for fitting a cooler MLT with a thermometer? I was using my brew kettle as a mash tun, and now have moved onto a cooler MLT. I have the exit valve on it, but I want to incorporate a thermometer into the cooler so I can monitor the temperature without having to open it up to check.
I was thinking of just drilling a hole slightly smaller or about the same diameter as the thermometer and push it through. How would you seal it if it leaks? Silicone calk?
