Product review (5 stars): Sturdy and accurate
I have several high quality instruments that I've invested in that have to be kept within a certain humidity/temperature level so that the wood doesn't warp/crack. I keep them in a room with a hygrometer but it's not a professional one and I questioned whether it was accurate. (It's made by Acu Rite)  Well, with this meter, I have discovered my suspicions were true, my old hygrometer was off by at least 5%. (I confirmed with a THIRD hygrometer that I borrowed from a friend)

This meter is wonderful; it's so easy to use, very durable and best yet, it can keep track of the data and tell you what the minimum and maximum readings were. It automatically shuts off if it's been left on saving battery life. The added case is also a nice bonus.
