Must see what reading also mah. If it's at 70+% sure got something wrong
You need to check the hygrometer to ensure the %RH is within the desired range (which is about 40-55% RH for lenses)
To kill the fungus in the cabinet, use a cloth dunked in soap solution and wipe the interior a few times. Then leave it in direct sun light for a few hours for a dose of UV. Instead of soap solution, you can also use a disinfectant.
Make sure you wipe all the corners or else even a small area of fungus will multiply itself again.

oh...I normally see the reading almost everyday before leaving for work. Cos at first I tot you mean need to use other means to see if the hydrometer is working. (e.g. using a hydrometer to check a hydrometer :bsmilie
I use silicon gel in combination with the box,
as long as silicon gel turns transparent clear color, that means it is not dry enough,
digital measurement is never as reliable as physical reaction.
meters can go wrong any way even you read
That's a bad idea as your %RH might get too low, because the silica gels absorb additional moisture from the air and they're not under the control of the dessicator. If you're kiasu just put another hygrometer inside the cabinet to double confirm.
Haha, I only have 1 additional hygrometer shared between my 2 60L cabinets.
