*by A***N on Reviewed in the United States on August 31, 2017*

This is an industrial grade thermometer that certainly works. The dial base is threaded for half inch pipe thread. Solid heavy and thick. I have not come up with a way to hang it in a pot yet, but it generally responds fast enough that I don't need to keep it in longer anyway.
