To try & pinpoint the cause of a condensation problem I'm looking for a combined thermometer and humidistat / hygrometer (AFAIK the same thing) to record and store measurements at intervals, eg once every 15 minutes over, say, a 24 hour period. It would be good if it could download to a PC, but not essential.
I've had a good hunt around the web & while I can find loads that will store a max & min at around =A320, I can't find anything that will just store readings at set intervals, which costs less than several hundred quid.
Any suggestions?
