I had two digital accurites in one of tubs this weekend, checking temps and humidity before putting my snake in there. I started with one, but I felt it was reading low on my temps so I put another in beside it. One read 72 degrees, the other read 77 degrees, both showed about 70% humidity. I replaced the batteries in both of them (out of curiousity's sake) and then one read 77 and the other read 76 degreees. It seems odd to me that a low battery would through the temp reading off, and maybe this was just a random one-off issue, but something that makes me wonder....
