Hi guys would like to ask for an advise. What is a good level of humidity rate should the dry cabinet be? I noticed that in recent weeks my dry cabinet humidity rate has been at the 55% - 65% mark, despite the dry cabinet is not open for days.
That will depend on the type of your dry cabinet. Some have small buttons at the front door to set the target RH. Many have a knob to turn, sitting inside the dry cabinet at the back where the electrical components are.
