How to a Add Thermometer to your Cooler Mash Tun
Monday, December 13th, 2010
I bought a couple Rubbermaid coolers to use for my All-Grain brewing, but the one thing they didn’t come with was a thermometer. I had been using a digital probe thermometer until one brew session the temp was off by over 30 degrees. last time I checked water doesn’t boil at 185° in New Jersey. So after a bit of searching on the internet for cheap ways to add a thermometer, I found a forum on homebrew talk that used a rubber stopper and a simple probe thermometer to inexpensively solve this problem.
