    Lead thermometer

    I'm after a lead thermometer for use with my Lee bottom pour and for ingot making from scrap lead (over a gas ring), and I'm looking for suggestions/options.

    Need to keep an eye on temp for being able to repeat results when casting, and to avoid approaching zinc melting temp (when I melt down scrap I get quite a bit of zinc wheel weights. I know there are ways of sorting them, but I can't be fucked, and just floating them off the top seems easiest. Accidently going too high with the lpg ring is too easy, and having realtime temp reading will make this easier).

    I had considered a high temp thermocouple like https://www.jaycar.co.nz/k-type-thermocouple/p/QM1282 for use with my home or work multimeter, but I dunno if it will stand up to an hour or two of use at a time. Cheap enough to just try and see, but if someone pipes and says " Yeah nah fuck that", that's a bit of time and coin saved init?

    One of those long probed thermometers with the disc shaped dial at the top seems to be the go, but I can only seem to find them in lower temp ranges, ie for cooking etc.

    What do you fellahs use?

    Yes, possible, but with both hands busy when casting, it'd nice to have a constant readout

    Also remember that zinc fumes will def have you puking your guts out. Ask any welder who's welded galvanised material.

    Arguing with an Engineer is like Wrestling a Pig in Mud.

    After awhile you realise the Pig loves it.
