So how do the temp probes work? I looking for something to measure temps when I finish up my intercooler sprayer this spring,
Many types of temperature sensors are available; thermocouple, thermister, infrared, etc.

A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end, which produce a small unique voltage at a given temperature. This voltage is measured and interpreted by a thermocouple thermometer
Thermocouples are available in different combinations of metals or calibrations. The four most common calibrations are J, K, T and E. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple.
Omega's Temperature probe reference sectionMany thermocouple thermometers use two junctions one for the probe one for control.
A standard multimeter measuring voltage won't give the best results for temperature readout. Not all probes have linear voltage over temperature. I'm not sure any are fully linear actually.
