I purchased a nice kettle pictured below and it came with the 3/4" ball valve and barb. You cannot see it here, but there are 3 more ports and one of them is nice and low. This is setup with the tri-clamp connections and I do not know much about them.
I think I have the ball valve and barb connected correctly.
I want to get a thermometer and the Blichmann Brewmometer looks really cool. My question is what type to I get and how do I connect it? I know that I will need to purchase another tri-clamp for this port.
