You just hook the thermistor up to a Multi Meter, reading ohm's you look up
the chart to convert to temperature.
Very accurate but you should do a table for each thermistor ( apparently
they are individualistic ).

There are only about three basic kinds so you might be able to find a
generic chart online somewhere. Also, thermistors are not linear by
nature, but if you put a resistor of the same value of resistance
as the thermistor (at your normal range of temperatures) in parallel
with the thermistor it will, in effect, linearize it!
