Optical Pyrometers are used all the time in many applications. Garage
mechanics use them in car repair to check hot spots on engines where
they do work on them. They are out there, but I can't give you a source
for one that reads cone 12 temps.
One source for the element wire is Euclids. Check them at their website
below.

Omega, a maker of thermocouples, readouts, etc. could help you, maybe.

Hey Clayman,
I looked around for an optical pyrometer several years ago, and found
several by just searching: "high temperature optical pyrometer"
Here's one:
http://www.pyrometer.com/Pyro_Optical.html
Don't know what they cost, but imagine more than I would want to spend.
As for the kiln elements reaching cone 12, it's interesting to look at what
most potters use, then what industry uses, where very high temperatures are
employed. Here's a neat article about heating elements:
http://keithcompany.com/Electric%20Heating%20Elements-577.aspx
When going to such high temperatures, often metallic elements are not used.
In any case you will probably be getting either Kanthal A1 or Kanthal APM
elements. The A1's are rated to 2550F and APM's are rated to 2600F. The
APM's cost 2-3 times more than the A1's. On another forum we've had lots of
discussion which element is better for high temperature crystalline firing
schedules and if APM's are worth the extra cost. Most think getting a
thicker A1 element is more cost effective. I would suggest you look into
14ga. Or even 12ga. A1 elements for your application. You may have
limitations depending on the size of the element groove in your kiln.
I use APM elements in my studio kiln for ^6 crystalline glazes. I have
gotten 65 firings without any loss in programmed heating rate. At school we
have the exact same kiln with 12 ga. A1 elements, and though it does not
have as many firings on it, I expect an long life for these elements also.
Here's an interesting article on element design published by Euclid's:

I believe Pyro still makes an optical model. FWIW, I believe
that infrared pyrometers these days cost less and are at least
as accurate.
