Just water temp, a cheap swimming pool thermometer will work, might not even cost $8 at your local cheep store.

Also those corded indoor/outdoor thermometers will work, you have to get the water temp in the outdoor side of things.

I have a YSI ODO Pro, that gives me both temp and O2, but it's still a handheld unit.
