APC AP9335T NetBotz Temperature Probe

The AP9335T is designed to connect to APC UPSes or NetBotz boxes to provide a temperature reading. I was hoping to see an IC inside the one I opened up, but its just a thermistor. It reads 9.8k Ohms at about room temperature, and resistance decreases with temperature. At body temperature it reads 6.9k. Pressed against an ice cube it reads 20k. Based on this, the thermistor seems to be a 2700k type.
