Howdy,
I need to calibrate the self-cleaning temperature of my oven.
It wants to be about 900°F.
I can get expensive thermometers that will measure in that range but this is a one time thing.
Next, I thought of pyrometric cones (that deform at specified temperatures) but I can't find anything in that temperature range as they are typically used in kilns and such at higher temperatures.
Can you think of a way I could measure the 900°F temperature that is reasonably accurate, but of modest cost?
Many thanks,
