TFA Cosy Thermo-Hygrometer SG

Having read reports about the effects of humidity on musical instruments, I was very concerned about my acoustic guitars. Although I live in a very damp British climate, having central heating on in the house for 6 months of the year is probably not good. I was rather shocked to discover how dry the atmosphere had become inside the house! The TFA Hygrometer gives a really quick visual guide, and helped me to remedy the situation by just opening a few windows to keep the humidity at a safe level. The Hygrometer is really sensitive - just hanging up some washing inside the house gives an instant change in the reading! Worth having one in different rooms.
