How to read Hygrometer ? :p

[ST_sg]

Sorry for this stupid questions, how to interpret the hygrometer on the dry box huh?

Which state is good for storing?
Blue 0 - 55%
Red 55 - 100%

Initially the meter was at 65% RED, after I put silica gels, over a night, it turns to 5% BLUE

Does it mean that, my drybox now is in good storing lens/cam condition? :dunno:

Appreciate if anyone can enlighten me :embrass:

Thanks in advance.

mine is always ard the 40+ mark, think should be ok as long as is not on the higher side, not very sure also, any one can help out. tks

between 40 to 50 should be ok. If it's too low, the plastic parts may harden.
