I've tried to use this probe to detect temperature from an arduino microcontroller.

Unfortunately, I can't seem to get a decent reading out of this. I need to know appropriate coefficients for steinharts equation if they are applicable to this type of probe. My attempts at finding these coefficients have failed with various measurements of resistance and temperature. It seems as though this isn't a NTC thermistor. Can anyone offer some guidance to interpret an analog reading from this probe?
