I have had this thermometer for probably a decade. About three years
ago, I accidentally put the K type probe into something too hot and
ruined it. Now it's time to get another probe, but I'm not sure which
one. I lost the info on the thermometer, but here is an image:

Suggestions for both a manual and replacement probe would be welcome.
Thanks in advance.

About half of my various digital multimeters can be used as a
thermometer using a Type-K thermocouple probe. Perhaps it's time to
junk your 10 year old meter and just use a multimeter? Or, perhaps
add some additional functionality, such as a data logger?

I can't deduce what style of Type-K probe you managed to destroy. So,
pick a photo that looks familiar as any Type-K probe will work.

I prefer the bare thermocouple end with the common yellow flat blade
type connector. For use on some instruments, I have an adapter to
banana plugs. The wire is usually fiberglass wrapped to handle the
heat. If I need a tip for better heat conduction or mechanical
attachment, I stuff the tip into a copper or brass tube, and fill with
whatever is handy. If I want accuracy, corrosion resistance, or high
temp, I use a commercial probe. For example, for a 1000C kiln:

Or, use tape or glue:

Hint: Perform a rough ice bath and boiling water sanity check on any
probe you buy. I've seen a few surprises and built a few defective
probes.
