I'm an idiot. I dropped (and broke) my thermometer/hygrometer while cleaning my 'bator. Now I'm having a hard time finding a new one. I found an AcuRite one on auction but the fine print said it was not suitable for incubator use. Ugh. So then I found this one. It has 2 probes for inside the terrarium and the actual meter sits outside the unit. Seems like it would work great--IF it is accurate. I noticed they do have a button marked "adj" which suggests they might be re-calibratable. I've found them in a couple of different places, all at about the same $19.95. Has anybody ever used one of these?
