I have a small 6"x6"x4" oven and need temperature control.
I am considering a Fuji PXR3 temperature/process controller and will need a thermocouple and a power switching device.
My electronic skills are pretty basic. I would welcome advice on what thermocouple, insulation and housing is best suited.
Should I choose a relay or a sold state relay?
Is there a better way to heat treat and case harden?
