Recently I found that one of my precious lens (which I have not used for quite awhile) has moulds on it.How do you know if your Dry cabinet is working or not?
My dry cabinet is placed in my store-room - is that a no-no? My dry cabinet has a gauge on it and it shows 75 RH with 30degrees C - does that indicate that my dry cabinet is not working?
i think you better get it checked. 75% RH is not exactly normal storage conditions. outside RH is 80-90% so it's actually not far off.
