Hi Phil
I have tried other hygrometers and they all seem to give a similar reading...I moved the salami to an air-conditioned room (15°c and RH 75%) for two days. I allowed the humidor to dry out completely and then put the salami back in.....after a short while the humidity started to climb again and settled at 85% RH. I used the same hygrometer for both measurements....my conclusion is that the cigar humidor is the problem...I suppose it is doing what its supposed to do..i.e. to keep cigars from drying out.
The humidor is not suitable for curing however, once the salami is almost ready, it is a handy item to have if you want to slow down the curing process for a while longer instead of vacuum sealing and refrigerating to stop further drying out.
...well I dont smoke cigars so I have an expensive humidor/wine cooler which looks fancy but doesn't really do the job....I obviously have not shared this information with my wife who felt that this was an unjustified purchase.
BTW I am doing this in Southern China where average year round humidity is in excess of 80%
