Questions about the accurate thermometer/hygrometer

So I have been hearing a lot of buzz about the accurite you can get from wal mart I picked one up today to put in my blood pythons tank, I’m guessing these are the most accurate as far as readily available temperature measurement goes? If so I picked up a digital hygrometer from one of the big box pet stores that is reading almost 10-15% humidity difference? I knew their was something wrong I live in south Florida and humidity is not very hard to maintain but it was reading 70 something % this morning and I thought no way the substrate is hardly even damp I pick up the accurite it’s reading closer to low 60s is this possible to be that far off? What are people’s general consensus on the accurite should I look into other forms of temp and humidity measurement?

I've been using Thermapro and Accurite the entire time I've kept reptiles and have had no issues. Now as far as how accurate they are, I can't speak for that. I'm not in a lab testing them of course lol, but what I can tell you is I experienced the same issue as you, bringing home a "reptile brand" digital hydrometer and getting wildly different results. I even ran a test once where I got a 4 pack of some brand, I can't remember which, but sat them right next to each other in my kitchen overnight, and you should have seen how different they were the next morning.

Long story short, I don't think you went wrong with Accurite.
