So I bought a Blichmann Thrumometer online thinking I could put it between my BK and pump to monitor the recirc before going into the fermenter. I had to check my temps with a digital stem thermometer about 20 times last Sat before I got it down to transfer temps. The Thrumometer showed up yesterday and I noticed a tag on the side that says "Do not exceed 140 deg". What a bummer!
I guess I'll have to figure out a plan B. Any sugestions?
