@sccsuk oh yeah, when i showed them -/+30C fluctiation in boiling water (80-110 is what it bounced between) they said it was "not hot enough to be accurate" BS. a proper circuit design can be accuate from -150 to +1200. AD595's are awesome chips and they used cheap unconditioned op-amps for TCs. TCs are non-linear and a simple op-amp wont do it right. plus the gain will change as the op amps operating temp fluctuates.

@sccsuk i am building my own controller for it using an arduino, 2 ad595 TC amps and a digital potentiometer for the lamp power control. display and controls are going to be handled by a repurposed HP LJ4 op panel. should be done in about a week. all the hardware is made. just got more coding to do.
