I would like to permanently install a grill/grate-level thermo. on my smoker, and I would like to find one with a capillary and sensor to the grates, and a gauge mounted outside. Does anyone know where I could find something like this? I know there's lots of digital units out there, and that's an option, also, like the Maverick et-73, but I was thinking of something permanent. Any info. would be greatly appreciated! Thank you for your time.
