Is this a K Type sensor?

Ditto on what Dave said about the wire colors. They will tell you what type of probe you have. Red/Yellow is type K.

The output from a type K probe is very low and you won't be able to use a PIC ADC to measure it directly.

I'm working on a project now that uses the MAX6675 sensor with a type K probe and it works very well and is super easy to read the MAX6675 and display to an LCD.

I've never used the AD595, but from a quick look at the data sheet it appears that the AD595 is good for measuring up to 1250C (2285F), but the MAX675 is only good up to 1024C (1875F), so depending on what your temperature requirements are, the MAX6675 *might* not read high enough for you...
