We all know how important it is to have accurate temperature readings throughout the whole brewing process but I was wondering if any of you guys could recommend a reliable and long lasting brew thermometer. During my last brew day I decided to get a second reading during the mash with a second thermometer and was surprised that they showed a difference of 2C. I tested them both afterwards in a glass of water and it was the same so it wasn't down to positioning in the mash. Both are digital, one with a probe on a wire and the other the stick type. 2C might not sound much but its enough to make me feel uneasy. If any of you guys know of a good and reliable thermometer out there I'd really appreciate your tips. Cheers. Paul.
