You'll have to figure it out by measuring or opening up the probe that you have.
If you are lucky, its a NTC divider inside the probe, 10k between two leads, then 10k NTC between adjacent lead. Measuring resistances between those 3 leads should confirm this.
If you are not so lucky, its something like a LM35 or DS18B20 IC in there. Then you'll have to build your own sensor or buy their version.
