Dry Box Humidity

How many days have you purchased the box?
have you checked:
Is the hygrometer analogue or digital?
Is the dehumidifier LED on?
all doors are closed properly, no camera straps in the way.
There's a knob adjusting the level of 'dryness' for the dehumidifier. have you adjusted it before?
Low to high?

Thanks for the fast reply.
mine is the dry box/case, not cabi. So the hydrometer is analogue. Have gotten it for 4 days already.
is your's the self-powered type or slica gel?
1. The hygrometer may be faulty.
2. otherwise, a simple explanation might be that the silica gel isn't enough to take out the moisture in the box.
I'm assuming the normal humidity of a room (without airconditioning) ranges from 85 - 90%.

Hi,
I used the silica gel which came along with the box.
I place it on the floor of an air-conditioned room. Anyway, I'm wondering. For dry cases, how do people get the humidity they want?
I use to have a drying box. actually, you can't really control the humidity. you just put in as much silica gel, and hope for the best!
I would suggest you buy a BIG bottle of silica gel: $43.500 to $4.50 per bottle.
fill up transparent film canisters, or a tiny ziploc bag.
place it in the dehumidifier.
i usually check to see if it changes rapidly to pink (too wet).
it it turns blue slowly (over a few days), or stays blue. then it's quite alright for filters and cameras.
check for leaks in the drybox....
good luck.

Hi aaron, i just got my dry box today. its those with a silica gel pack in it. In the beginning it shows 70 and after opening it to fill in my eq, it somehow went close to 80. later on it will drop to about < 60. Trick is --> OPEN UP THE SILICA GEL PACK PLASTIC COVER. hehe hope it helps.
Hi there,
I have opened up the plastic cover.but it's still at 70+. Is there another plastic cover inside the silica gel box?
I've got a dry box also but I find the silica pack that come with it quite useless. I poured in a bottle of silica gel I bought separately and immediately the next morning, I find the hydrometer dropped from 70 to 40. Guess what, I've changed the silica gel i separately poured in twice since, because they turned pink but the original silica pack that came with the box is still dark blue. I guess they are useless at absorbing moisture. Hope this helps.
In this case will it help if I replace the existing silica gel with the silica gel I bought? Like pour away the existing one. WIll it help?
hi just to share 
, on my side I used Air-tight box (toyo) to store my prosumer cameras. If you used silica gel. At first, the gel will turned pink very fast as it absorb moisture from the content (camera,lens...) and the humidity inside. I normally will need to change it after 1 day.
After the 2nd or third silica replenish cycle (depend how big the box and inside contents). The gel will turn pink more much slowly... (normally will last about 2-3 weeks)
Now I have switch to those electric dehumidifiers for all my air tight boxes. More eco friendly as it can be reheated and reuse. If you are interested do a search for the threads (quite a few of them talk about this device)

Switch on your air-con and wait for your room to cool down to around 22 to 24 C before opening your dry case. At this temp, the typical humidity of your room should be less than 50%.
Open your dry case and the humidity inside the box will be "absorbed" by your room. Wait for a while, and you should see your meter giving you less than 50% RH (if it still show 70%, perhaps your meter is faulty). Close back your box, and when you switch off your aircon, the RH inside the box should stay around the same % RH assuming there is no leakage on the box.
If you want to save on your silica, try only open the box everytime you switch on your air-con.

I have published an article here that might help you understand the need for an electric dry cabinet and information regarding humidity levels. http://shimworld.wordpress.com/2007/06/26/wonderfully-dry/
