What multimeter works well for this and how to add connectors for it?

Any meter what is going in the DC millivolt range.

How hot can the wire get? It's stainless and fiberglass, does it need shielded from flame?

I’ve had mine directly in the flame and glowing at 1900 degrees with no issues in the forge.

Is there a datasheet and user manual available?

The manufacturer can give you the answer.

is it ok if i use it for a max temp. of 800°c? (to unwax molds), I have seen people complaining about problems with higher temperatures

I do not know, it is reded for 100 C to 1250 C it should be working.
