For a brew kettle, water kettle or lauter/mash tun…
I’ve seen the ones on the Gucci/Fendi brew stuf sites. $60 + if you order WITH your $700 tub. Ain’t happening. So, where does one find a nice cheap but reasonably accurate thermometer I can mount on a kettle, cooler… etc.
Austin Brewing Supply has a non-Bichmann bolt-in thermometer http://www.austinhomebrew.com/product_info.php?cPath=178_67_65&products_id=12725
but you still need a bulkhead for it, which puts the total price back up close to the Blichmann version.
I haven’t seen a bolt-in thermometer configuration that’s less than $35-$40.
