Don't know if anybody responded, or not.
But first I would change your interface to include analog signals (I firmly
believe in never blinding the computer to what's really going on)
Second, the only IF temp meters I remember were made by Raychem, or such
back in the 70's. But they at least have to have an analog output to
interface to your computer.
Third, write the testing program in the highest level language possible.
(else support will be pure hell)

>We are testing 2 coil windings (at a same time) for resistance using 4
wires Kelvin connection. Acceptable (Pass) Value ranges for the parts are:
Part A 2.3 - 2.7 Ohm Part B 5.4 - 5.8 Ohms. We want to know if the part is
within (good) these ranges or out (bad) of these ranges. We should be able
to connect your output to our digital PLC I/O Card, or simply to trigger a
>relay. (NO RS-232)
>
>In the station prior to the testing station, terminals of the coil winding
are being dipped into soldering pot resulting on the temperature increase,
which then effects our resistance readings.
>
>We want (ideally) to measure the temperature of the part using infrared
sensor, inputting that into the tester and compensating for the temperature.
This would require a tester that would be able to do some computation.
