You can probably cut the wires back to where the insulation is not
melted and twist them together vrey tight and it will read the
temperature at that point. If you could weld, not solder the wires
together it should still work.

If you want to measure liquid temperture, the wires do have to be
isolated from the liquid. Any thing that conducts electricity between
the wires will cause a false reading.

It is probably showing the incorrect temperature in your mouth because
the liquid or skin resistance is causing a false voltage between the
wires without insulation.


Interesting, so even the welded wires still have to be insulated then.
As you say, the reason for the faulty readings I am getting.
Unfortunately, I don't have anything decent other than shrink tube and
leftover high temp RTV to coat them with, so I think it's time for a new
probe.

I will point out that the group has been a big help in informing me how
these work and my thanks.
