temp monitoring close to an RF plasma?

I'd like to measure the temperature near a RF plasma generated with a power of 1 kW. The plasma is inside a low pressure aluminium chamber. I've used liquid crystal temp "badges" that change colour. Would like something more real time.

RE: temp monitoring close to an RF plasma?

depending on the temperature ranges you're looking at, you might try using a fiber-optic sensor system made by FISO technologies (www.fiso.com)--I think their sensors go up to about 200 C and have an accuracy of about 0.5 C. We have one of their systems and have been happy with it---costs a lot more than liquid crystal stickies, though!

Thanks sford
A rough idea of cost would be useful.
