Hi ,

I bought a Sun Dry cabinet for my DSLR and wondering what is the correct setting? There are Low, Medium and High setting for the dehumidification and what is the average %RH for cameras and lenses? Thanks

55% of humidity

If Aipo drybox, recommended around 40-45%

mine is set to 45% humidity............what brand? dont know sun-something

mine's around 40-50% RH. according to various sites thats the recommended setting for storing lenses.

I am using Sun Dry Cabinet and whatever setting I put, the RH% is around 30-40%. How?

there is something for u to adjust one right?
my one come with a manual
60-55% Painting, antiques
55-45% Cameras, video cam, films, negatives, cigratte..
45-35% semiconducters, medical supplies
35% seeds, pollen

If too dry i scare the plastic will on too dry condition?

I have the setting but there are L, M and H setting and whichever setting I put, the %RH is below 40% eventually. The setting can maintain the humidity.

i think they might be a leak on your dry cabinet.
Please check with your supplier.
They ideal humidity level is 45%, or can be between 40%-50%

how to know if my silica gel is used up or not.

mine is in a white paper bag. so cant see the colours!

argh

from what's i've read, silica gel will always dry up the humidity. If it's been use for long, it can always be recondition back to previous state.
You can try reading these here

but the problem with silica gel, you could never know the humidity level within your case/box.
The amount you put, might be good, or might me too much. If too much, it will drain your gear moisture, if too little, it will never protect your gear.
One thing i can advise you is to get a hygrometer. This meter shows the level of humidity in contain case/box. Therefore you could know wether you have enough silica gel or not.

hope thats help.

too dry will dry up the rubber parts inside the cam or lens. end up it become hard n brittle

analog cabinet setting guide-
1- set the dial at center. let the cabinet to stable for one day.
2- obtain the reading from the meter.
3- if reading is lower than ur desire range - reduce the power of the dry module ( turn the dial abit only).
4- if reading is higher than ur desire range - increase the power of the dry module ( turn the dial abit only).
5- repeat the process 1-4 until u happy the humidity level.

Note : need to be patient!! accuracy >+- 5 %
Note : pls note is normal the reading may drop futher after few days.
Advice : As the reading around 40 - 50% consider ok already

Analog cabinet user
< 30% not ok
30 - 40 % - ok
35 - 45 % - ok
40 - 50 % - ok
45 - 55 % - ok
> 55% not ok

45% to 55%

break the paper bag and see lo. but silica gel got disadvantage le, bcos it will dehydrate your lens or camera rubber thing, so better use dry box

im using one 2...i am currently setting it at M.but not exactly at M but alitle bit higher.i got 40 RH

I would seriously advise against putting the silica gel into the microwave oven. Especially if you're using it to cook/warm up food.

The silica gel(colored ones) are extremely carcinogenic.

Hi Crownfish,

You are absolutely correct, this the correct way to set your analog (dial type) dry cabinet. User needs to be very patient, it will take a few hours (6-10) to stabilize. I took 3 days to set mine.

If you want a easier way to set then get the digital type because you set the dial at 45% and leave it for few hours and then you can straight away put in your lens.

I have mine like that as well, I finally rip the white paper bag, and just put it like that.

Another alternative way is to buy from the camera shop. I last purchase mine at Mid Valley at RM 15 per bag. (it is a see through type).

Add on info. I use my dry box to keep stuffs at home and use silica gels in my camera bags.

makes it safer
