The BrewMometer is a great addition to any brew pot as it helps give you an accurate temperature reading of your wort at any time. The weldless version features the standard 3" dial face, a fixed 2" temperature probe, and can be easily installed into any stainless steel brew pot with a 1/2" hole using the unique weldless bulkhead. The weldless design offers unequaled sealing and stability as compared to other designs that are prone to leak and "wobble" on the pot.
