Review on Thomas Traceable Waterproof Thermometer with Probe/Cable - Temperature Range: -50°C to 300°C by Todd Stovall

That was my second. The first had to go back to the Revain because it wouldn't turn on despite changing the battery. The second worked great on 2 beers and then in the middle of a triple brew mash it went crazy and now it's showing 134.7 as the ambient temp. So I changed the battery again. Still says it's hotter than a day in the Sahara. I wrote to Thomas Scientific hoping they could fix the bug so we'll see. Maybe the 3rd time will be a spell?
