The hydrometre looks sturdy; it is small and light and velcro can be attached in your case. But it is not accurate...themometre seems okay but the there are not decimals. The hydrometer is not very accurate; I have other two hydrometres and the readings are almost identical. The Stretto's hydrometre readings are about ~10% more than the other hydrometre's readings. Also I find the product too expensive. There are more accurate and cheaper ones out there. I am already looking to sell mine.
We use it to monitor temperature and humidity in the practice room / studio. We just attach it to the wall with some velcro, and everyone has easy access to it. Very small and light. Even if a bit pricey, it's been in use for a some time, without replacing batteries, and giving accurate read outs. Recommended
