I bought the same thermocouple, it does not seem like it'll live underwater. But if you use a heat shrink tube with adhesive lining it seems that you can use it.
But if you look at type of thermocouples (http://en.wikipedia.org/wiki/Thermocouple#Types), it seems like types J and T provide a better range for sous vide application as they have lower temperature limits.

Chris, Akiba, Anybody,
I'm pursuing a sous vide for my friend John.
i understand that Chris Shannon bought a thermocouple from Akizuki.
Looking online, I only found at Akizuki the one shown at the link below.
The temp range is way overboard, but would it live in water?
Thanks,
Jud

No.
You need to waterproof it. The easiest is to get a heat-shrink tube,
stuff some piece of plastic (cotton bud stem?) at one end, push the
couple and make sure you have long enough tube (going way out of the
pot). I think heat-shrink will be good to 100C, test to be sure.
What we did in the lab,
get some test glass and add the temp sensor including wire down to the
bottom. Fill up the entire tube with epoxy.
You end up with a food-friendly glass surface and it is water proof.
One point which could be both advantages or disadvantage... the glass
and epoxy act as a low-pass, it takes time until a sudden temperature
change is showed correctly.
However, for safety reason I would never drop the head of the glass in
the water... always let it stick out.
