Product review (5 stars): works great
This pocket temp/humidity pen is exactly what I needed. I have an egg incubator that moves the eggs, so bigger weather recorders got in the way. not only can I check on temp./humidity it also tells me the max temp. so I'll know if it has gotten over heated. It's very easy to read, the only thing that could make it any better is if you could choose to light it up and leave it lit. Then I wouldn't have to open the incubator as often.
