Just want to seek advice frm bros here if anyone encounter such situation.
I bought a analog type dry cabinet from one of the bro here, then i went to buy another digital hydrometer and place side by side to the analog hydrometer, then i went to turn the knob.. on the digital its show 47%RH but on the analog it's show 57%.. it different by 10!!.. both about the same temperature.
so is this situation common? or is the dry cabinet spoilt?
