I have a fairly accurate hygrometer. I bought it from a scientific instrument supply company. I have been using it for the past year and have been delighted with the performance. A description of it can be seen at http://www.hannacan.com/fiches_techniques/HI98601.pdf Up here in the far North we have just been going through a cold spell with an mass of Arctic air over us. I knew it was dry in some homes, have had the humidity down to 5 to 8% at times, however this is nothing compared to some public buildings that have music schools in them. I was in one yesterday that recorded 2.7 percent in one room and this evening I was in a building that actually took the gauge down to 0% for a few moments. I did not know this was possible, however I guess it is. It must be like sitting right inside the furnace. Some of the local piano salesmen tell me they sometimes hear things go crack on the showroom floor. I wonder why? We even have laminated boards that crack in this part of the world. Keeps us busy though. Install lots of Dampp Chasers around this time of year. Chris
