Can a tube be put on the end of the probe to be able to sample from areas too far down for the probe alone to reach?

Yes it can. The end of the probe has a barb so a 4-6mm ID tubing will work. Thank you

What is the indication if the O2 level is above 30%?

If above 30% indication is 30.0% and does not change unit after this.

can this device be used to warn of O2 depletion in a room where a liquid Nitrogen duer is stored?

Functionally speaking yes it could do that. However, for continuous room monitoring to alarm for oxygen depletion we recommend permanently fixed wall mount unit, like this guy here: https://www.amazon.com/dp/B0843JLSXS?ref=myi_title_dp
