depends on whether you left the silica beads in the container or spread them out... And to be honest, there's no need for silica beads in a dry-box - you'll only need silica beads when you've got a normal container with no dehumidifying function. And after some time, they stop functioning as well (when they change colour). =)
hey Chong, when you it doesn't go down, what was the reading at? it takes up to 12 hours sometimes especially when u start using it before it responds (since the stuff you put in could have lots of moisture on their surface for example).
i have an old Toshiba electronic drybox which runs below 30, prob is that i can't find any switch/levers to adjust (maybe don't have) and i've lost the manual. as someone mentioned, i also resort to opening/closing the door once in a while to let the gauge go up higher than 30
I did not know that at 20%, the lubricants in the lens will dry up. Learnt something new today.
I have already tune my Value dry cabinet to mid-range rate of drying, but the meter still goes down to 20% overnight (no sliica beads in cabinet). Hmmmm...think I better set the meter to low rate of drying.
Thanks guys! Lucky I bumped into this thread.
hmm my dry box can never go below 45% and once it open it will shoot up to 55% and it will takes about 1 night to go back down to 48%, to get 45% i cannot open the box for a least 3 days. Never know that it can do below 20%.
