It is specific but there are only a few types. The differences are, generally, the connector and the value of the internal resistor.

Best to find a manual the unit or, failing that, open it and draw out a diagram of the input circuit. That circuit will come from the probe connector to the range switch. You can write down the values of the various resistors, compare to the voltage range, and reverse engineer the value of the probe resistor.
