What is a good, trustworthy, hardy thermometer/hydrometer to use for reptiles? I have one I don't 100% trust and am looking to get it replaced. Any brands anyone has had luck with? I'm looking for one that is not overly expensive, but if lots of $ is the price to pay for reliable info on heat/humidity I am willing to pay it. And what about thermometer guns (or what ever they are called) for checking surface temps? Any good brands of those? Thanks a lot.
