Quick question about a humidity meter...

Hey guys! it's me again.. so first I wanted to give you a nice update about my snake so here it goes: I got my new terrarium and I moved my snake to his new home :) I'm still giving him a little bit of time to adjust and I think he likes it :)
the temperatures are good I keep checking them with my temp gun :) but here is my question:
can anyone recommend me a good humidity meter..
it can be with a temperature meter too I don't care :)
thanks! and I'll post pictures soon!

Walmart carriers accurite digital hygrometers/thermometers, they measure both humidity and surface temperature with a probe. Most hardware stores carry thermometer/hygrometers, they usually say "indoor/outdoor" so you can use the probe to place "outside" if you were using it for its designed purpose - or you can use that probe to measure the surface temp of a heating pad or something similar.
