Thread: Dry cabinet hygrometer

    Default Dry cabinet hygrometer

    Hi, just curious to know a few things. My existing Digi-cabi DB-036 has been set to around 45%. And i just got a new one from CK Tang brand name is VALUE. No matter how i set the internal know, be it from dry to moist, it always remain at 40%. Is the hygrometer working? or is 40% normal?

    According to the guys from CK Tang, he mentioned that to try out the cabinet, normally has to set all the way to dry (at 20%). Once it reached that level, it's consider working. Then when i added in my camera and lens, and set the internal knot to around 1 o'clock position, it will slip all the way to 30% - 40%. Is the cabinet working or i need to ask CK Tang to replace it? Any advice? Thanks.

    It might take quite a long while (maybe a day or more) to reach 20%.

    To check whether your hygrometer is working, leave the door open and check the humidity. Singapore humidity is using >70%.

    When my cabinet is loaded, it can take up to 2 days to reach the set point of 40%.

    Or can get another from Homefix to be sure.

    So far the testing show it's ok. But my concern is that leaving RF at 40%, is it alright for camera accessories (lens, camera, etc)? My existing Digi-Cab is at the region 43-48%, but the new one is >40%.

    From articles, camera equipment is best at 45%-50%.

    Within the 40-50% range is ok.
    Do note that each hrgrometer has a 5-10% tolerance range.

    Sorry, just to correct some error.

    What i meant is that even thou i turn the know towards moist, it still show me between RH 35-40%. This is worrying in view that it may be too dry for the camera. Then i dun understand why leaving for days and setting still cannot stay standard. Even at 1 o'clock position as recommended by the salesperson, or i adjust towards moist (11 o'clock), the RH hygrometer will still show <40%. Is the cabinet spoilt and not working perfectly? Should i ask for replacement?
