    Maybe you really do need a tempering furance then .

    What sort of cycle time are you using on the SSR's?

    Hi Stuart,

    Yes, the tempering furnace is a must. I'm thinking of making a smallish benchtop unit that will run off a single 10A outlet and still be capable of 1250 C performance.

    The cycle time is several seconds, that seems to easily hold to better than 1 C, but then I'm not disturbing the equilibrium....

    Regards
    Ray
